New Antennas for Satellite Communications and Earth Observation

Antennas are the ears and eyes of the satellites and allows them to communicate and deliver the information to the users. There is an historical trend to improve the efficiency of satellite antennas in all aspects. Larger sizes, more power handling, lower passive intermodulation, more flexibility and adaptability are required and always taking into account the special needs of space applications. Satellite antennas need to keep all performances in a very harsh environment including extreme temperatures, high radiation and launch loads, all with a minimum mass and compact enough to be fitted into the launchers fairing. Satellite antennas have large differences depending on the orbit of the application, from Low Earth Orbit (LEO) to interplanetary missions. A look around different applications and orbits will be presented showing the latest trends in the different solutions that are used.

Extreme Wave Phenomena Based on Metamaterials

Metamaterials are artificial materials with electromagnetic properties that go well beyond what offered by nature, providing unprecedented opportunities to tailor and enhance the interaction between waves and matter. In this talk, I discuss our recent research activity in this area of technology, with special emphasis on the opportunities offered by metamaterials for wireless, radio-frequency and mm-wave applications. In particular, I will discuss how suitably tailored meta-atoms and careful arrangements of them can open exciting venues to manipulate and control electromagnetic waves in unprecedented ways. I will discuss our recent work on metamaterials for scattering suppression applied to antenna technologies, metasurfaces to control wave propagation and radiation in extreme ways, circulators and isolators that do not require a magnetic bias, and active metasurfaces for next-generation wireless systems. Physical insights into the exotic phenomena underlying these device functionalities, new technologies based on these concepts, and their practical impact will be discussed during the talk.

On the Modelling, Design and Characterization of Pulsed Photo-Conducting THz front ends

The power available from Photoconductive Antennas (PCA) by exploiting pulsed Optical-to-THz up/down conversions was so far only sufficient for localized spectroscopy. This has been a bottle neck for the wider use of these type of sources in sensing. However, recently reproducible m-watt power sources in the THz spectrum have been demonstrated by the THz Sensing Group. This talk will address some of the difficulties that hindered the progress for many years. The most important were likely associated to wide band modelling of short Electromagnetic pulses in complex active passive environments. Also the difficulties in manufacturing and interpretation of the measurements will be addressed.

A Holy Grail Quest: The Concept of Stored Electromagnetic Energy

In this talk the quest for the “final” expressions for the energy stored in a radiator is overviewed. First, the several forms of power and energy that have been defined and used in electromagnetics over the last 100 years are briefly summarized, and their most important characteristics are discussed. In a first step, frequency domain is considered. Starting from two power balance equations, a field based reactive energy is formally defined and compared to the numerous “definitions” already available in literature. Then the concept of recoverable energy is introduced. The differences with reactive energy are pointed out. Moving to time domain, it is possible to write unifying expressions generalizing the concept of reactive energy. It is shown that recoverable energy is just a special case for a specific current evolving in time. Illustrative examples are given where these energies can be used to solve practical problems. The paper clearly illustrates that the concept of stored electromagnetic energy is still not well-understood when a radiator is involved.

Microwave and Millimeter-wave Imaging in Real Time

Real-time microwave and millimeter-wave imaging methods are the workhorse in applications ranging from synthetic aperture radar, which operates with far-field data, to nondestructive testing and medical imaging, which employ near-field measurements. Research in this field is intensifying due to the rapid expansion of the wireless technologies beyond communications and into imaging and sensing. This expansion is fuelled by the advances of on-chip millimeter-wave to sub-THz electronics and the envisioned integration of communication and sensing in the future (beyond-5G) wireless networks and devices. This paper is an attempt to explain, categorize, compare and contrast the real-time imaging methods and algorithms within a common mathematical framework so that this interdisciplinary subject is rendered more comprehensible and accessible to the wider research community.

Recent Developments in the Design and Realization of Advanced Electromagnetic Surfaces

Advanced electromagnetic surfaces (AESs) comprise a spectrum of artificially engineered surfaces for manipulating the temporal and/or spatial dispersion of electromagnetic waves, and include structures such as reflectarrays, transmitarrays, frequency selective surfaces, polarizers, and most recently, metasurfaces / metagratings. The design of such surfaces can be separated into two steps: a macroscopic step, where the surface parameters required to achieve particular manipulations of the incident field are determined; and a microscopic step, where the geometric structure of the underlying unit cells or meta-atoms is determined to realize those properties. This talk will review recent developments in systematic design techniques for both steps. In particular, synthesis methods will be described for carrying out the macroscopic step, particularly for spatially-dispersive AESs used to implement specific radiation patterns. Subsequently, a variety of techniques for solving the inverse design problem associated with the microscopic step will be presented, with emphasis on recently developed techniques based on machine learning. A selection of AES designs developed based on the proposed techniques will be presented, including experimental demonstrators of several metasurfaces.

Nondestructive Material Measurements

Nondestructive measurements are often employed for characterizing electromagnetic materials, especially in non-laboratory environments.  Nondestructive techniques are fairly well established for simple media (i.e., materials that are linear, isotropic, homogeneous and time-invariant).  However, the past decade or two has seen considerable interest in materials that are non-linear, non-isotropic (e.g., hyperbolic and bianisotropic media), spatially varying & dispersive (e.g., wire media), time varying (e.g., spacetime metamaterials) and non-reciprocal (e.g., topological insulators).  What types of nondestructive techniques can be utilized for these materials?  What new theory must be developed and what new measurement devices need to be invoked?  What are the future challenges of nondestructive material characterization?  How has 3D printing shifted the paradigm of the meaning of nondestructive evaluation?  This talk will provide an overview of modern nondestructive material measurement techniques and will address the many questions and challenges one encounters when dealing with nondestructive evaluation of contemporary materials.

Massive MIMO and Drone can realize paradigm shift for wide and high-speed area in 6G systems

In the 5th generation mobile communication system (5G) and beyond 5G/6G, not only microwaves but also millimeter waves are used for further capacity enhancement. However, in an environment where the line of sight (LoS) between the base station and the terminal cannot be guaranteed, a sufficient communication area cannot be obtained. In this talk, a new concept of a system that dynamically forms the communication area of a 5G system using MIMO and unmanned aerial vehicles (UAVs) such as Drones is presented. The proposed system realizes the wave source estimation by UAVs for 5G system and a new area is estimated by wave source estimation results and machine learning via massive MIMO BS and UAV transmission. The initial results for the proposed system are presented.

Antenna-on-Display (AoD) for Near, Mid-and Long-range wireless applications

Electronic devices equipped with high-resolutions display panels with the capability of high-speed, low-latency wireless communication are becoming increasingly popular. State-of-the-art wireless generations such as 5G, ultra-wideband (UWB), Wi-Fi 6 will rely on the implementation of efficient and intelligent radio antennas. However, the evolution of display panels such as foldable, stretchable, breezeless and large-screen displays have triggered the need to reevaluate antenna design strategies and methodologies. Classical antenna theory professes the radiation efficiency of an antenna to be proportional to the effective antenna volume. Given the fact that conventional antennas have been designed and implemented as independent components, antenna radiation and performance suffers as the antenna real estate is further decreased amid the increased portion of display panels within a device. This eventually leads to performance degradation of wireless devices which use the latest display panel technologies. This talk introduces the original concept of incorporating a transparent, optically invisible antenna circuitry within the display panel. Denoted as an Antenna-on-Display (AoD), this approach demonstrates that electromagnetic fields can be generated and controlled within the view area of the display. This concept is applied and demonstrated across a variety of different wireless standards such as GPS, Wi-Fi and millimeter-wave 5G and 6G.

Chip-to-Chip THz Communications – In Pursuit of Ultra High Throughput, Super Low Latency, High Reliability, and Minimal Energy Consumption

Reliable, high-speed connectivity with low energy consumption and latency is a fundamental need in data centers. The use of wires and optical links in current data centers precludes adaptive scalability and suffers drawbacks in terms of assembly cost, airflow blockage, maintenance, and lengthy service time. It has been envisioned that future data center interconnects would alleviate the aforestated problems and introduce a higher data rate and low-latency communication. In this talk, we will discuss various opportunities, challenges, and current experimental trials in an effort to accomplish this in future data centers with the use of wireless Terahertz (THz) technology. We will show how these performance objectives can be achieved by affording data rates of up to 1.5 Tera-bits-per-second (Tbps) at a low power consumption of about 2.75 pJ/b (Energy-per-bit value), latency of 4.78 ns and good signal fidelity that ensures a Bit-Error-Rate (BER) of 10−12.

He is member of EurAAP, IEEE and the antenna expert group of the German VDE-ITG.

Industrial design of active antenna arrays

From a theoretical and conceptional point of view, active array technology can be the basis for powerful and flexible antenna solutions for many applications. However, when it comes to the industrial realization, there is always a danger of ending up with a very complex system, suffering from e.g. high material costs, a complex assembly process and/or a heavy weight. Therefore, the industrial design process of active arrays starts with a careful selection of the material baseline in combination with an application specific tailoring of the antenna to the functionality needed. The design process applied is very much based on efficient 3D EM modelling of the whole system including all details of the antenna and the integration scenario. By using a modular approach, one can combine high design and tailoring flexibility with affordable production costs. The presentation gives insight into today’s industrial design process and shows several examples of active array antennas realized e.g. in aluminum, plastic molding, organic substrate and LTCC. Based on latter systematic design process, the active array technology can provide very powerful industrial solutions at medium complexity and acceptable costs.

Numerical Weather Prediction models for the simulation of propagation impairments on Earth-Satellite communications.

The C to Ku frequency bands currently in use are becoming more and more crowded, whereas there is still a need for new services. Increasing the frequency to Q/V band increases the degradation due to the troposphere: not only rain, but also clouds, gases and turbulence are affecting the propagation. Radiowave propagation models for geostationary satellites links are available worldwide in ITU-R Recommendations. In the absence of Earth-LEO propagation measurements, however, only statistical models are available for non-GEO links and they were not validated against measurements. Numerical Weather Prediction models produce meteorological parameters that can be used to simulate the degradation of the GEO and non-GEO earth-space links. The talk will illustrate the results already obtained, their validation with existing GEO measurements and finally underline the potential of this method but also its limitations.
