Detailed Program

Block I: Foundations and Architectures of Reconfigurable Surfaces and Arrays

Device-level foundations of engineered surfaces and reconfigurable apertures, covering surface-waveassisted metasurfaces, reactively loaded metasurfaces, and electronically reconfigurable transmitarrays.

09:00 - 09:30, George V. Eleftheriades (University of Toronto, Canada)

Advanced Beam Manipulation with Metasurfaces and Related Structures

Abstract: Recent advances in metasurfaces will be presented for achieving electromagnetic wave beam-steering and beam-shaping in the far zone. A paradigm shift will be presented on how to implement engineered surfaces that can provide complete control of the transmitted or reflected waves, thus enabling both beam-steering and beam-shaping, without the need of any loss or gain. The key enabling feature is the utilization of surface waves to change the phase of the manipulated waves, while allowing for amplitude control through power redistribution. To demonstrate this concept, several surface-wave-assisted metasurfaces will be discussed, including architectures for steered, shaped, and multiple beams, electrically thin reflectors that minimize frequency-dependent beam squint, and electronically reconfigurable prototypes. New phased-array topologies with reduced complexity and cost will also be introduced.

09:30 - 10:00, Anthony Grbic (or Malik Almunif) (University of Michigan, USA)

Beamforming with Reactively Loaded Metasurfaces

Abstract: The talk describes how a metasurface connected to reactive loads or networks can serve as a low-cost beamforming technology. The reactively loaded metasurface consists of a grid of subwavelength unit cells connected to individual ports. Some ports are directly excited while the remaining ports are terminated in reactive loads and function as parasitic radiators. Strong coupling between the unit cells, tailored by the reactive loads, allows energy to be shuttled across the aperture to enable beam steering, beam shaping, and multiple beams driven by separate feeds.

Advanced Beam-Steering and Polarization-Agile Transmitarray Antennas for 5G and Satellite Communications: Innovative Architectures and System-Level Trade-Offs

Abstract: This talk presents recent advances in the modeling, design, and experimental validation of electronically reconfigurable transmitarray antennas based on p-i-n diodes operating in frequency bands of interest for 5G and satellite communications. Several architectures enabling dynamic beamforming and polarization agility with coarse phase quantization and reduced hardware complexity are reviewed and quantitatively compared in terms of antenna performance and energy efficiency, with implementation trade-offs discussed. Novel high-gain, low-profile architectures using sparse arrays as primary feeds are described, showing that, by co-optimizing the feed design and the transmitarray, the overall antenna thickness can be reduced to only a few wavelengths while maintaining high gain and wide-angle scanning capabilities. Finally, the proposed transmitarrays are benchmarked against conventional phased-array architectures from a system-level perspective, highlighting their respective advantages and limitations in terms of scanning capability, power consumption, efficiency, and integration complexity for next-generation wireless communication systems.

Enabling Next Generation Wireless Communication through mm-Wave Reconfigurable Intelligent Surface (RIS)

Abstract: The mm-wave 5G and beyond communication systems significantly improve the data rate, user capacity, and latency; however, the electromagnetic wave propagation suffers from high atmospheric attenuation compared with the sub-6 GHz bands. The quality of wireless communication is thus severely affected in environments with multiple obstacles, and coverage is typically limited to line of sight. Reconfigurable intelligent surfaces (RIS) can help by providing a secondary line of sight: RIS is a specially designed periodic structure that can be reconfigured to reflect the EM signal in the desired direction, making the wireless environment controllable and programmable. Despite the growing interest in RIS and the substantial theoretical work reported by the communication society, there is still a dearth of published works demonstrating practical implementations and experimental results, particularly for wideband RIS covering complete mm-wave 5G and beyond bands. This talk first introduces the fundamental concepts of RIS, then presents the EM design, prototyping steps, and complete experimental characterization of a wideband RIS covering the mm-Wave 5G band (22.5 - 29.5 GHz, ~27% bandwidth) with a beam scanning capability of 50°. A wideband mm-Wave RIS design that is fully screen-printed and uses novel printed switches based on vanadium dioxide phase-change material is then presented, followed by a RIS design realized through an optically transparent metallic ink.

Electromagnetic Skin Engineering: Toward Intelligent Wave Control in Smart EM Environments

Abstract: The capability to engineer electromagnetic wave propagation through advanced yet cost-effective technologies has opened the way to a broad spectrum of transformative applications in Smart Electromagnetic Environments. Within this framework, Electromagnetic Skins have emerged as a powerful enabling technology, offering new opportunities for the control of wave propagation in wireless communication and sensing systems. Realizing these capabilities has required extending and reinterpreting the traditional concept of metasurfaces, both in terms of achievable functionalities and underlying design methodologies. Despite the remarkable progress achieved in recent years, several fundamental challenges remain open, particularly at the physical-layer level. This talk presents an overview of recent trends and advances in the synthesis, engineering, and application of wavemanipulation devices for wireless communications, covering constrained design methodologies based on non-radiating current distributions, advanced electromagnetic field control for both fixed and mobile wireless links, and the development of next-generation low-cost Electromagnetic Skins for future integrated sensing and communication systems.

Intelligent Reconfigurable Array Architectures for Next-Generation Wireless

Abstract: This talk covers recent advances in reconfigurable array architectures for next-generation communication, sensing, radar, and satellite systems. Starting from intelligent small antennas with wave steering, multiple novel phased arrays are presented, including metasurface antennas with dynamic amplitude and phase control, phased arrays utilizing amplitude modulation, and leaky-wave antennas with combined amplitude and frequency modulation for dispersion manipulation. The discussion extends to digital arrays incorporating phase and polarization modulation, 2D digital arrays, and dual-polarized phased arrays with full phase and amplitude control. Finally, a beam-switchable digital conformal array with metasurface phase compensation is discussed. Collectively, these architectures enable wideband, multi-beam, and wide-angle scanning performance. The talk highlights how such reconfigurable and intelligent arrays, bridging phased arrays, digital arrays, and conformal designs, can be integrated into future wireless systems to enhance beamforming flexibility and operational robustness beyond conventional phased arrays.

Over-the-Air Characterization of Active Phased Array Systems

Abstract: Modern complex active phased-array systems typically have a multitude of beamforming settings, and to ensure reliable and high-quality performance, these settings have to be measured and validated. The RFICs and antennas of these systems are typically tightly integrated, which makes the characterization of such arrays non-trivial. This presentation explains the principles of the reverberation chamber (RC) and how this type of chamber can be used to characterize the active RF circuitry while it is connected to and loaded by an antenna, in a fast and accurate manner. Several over-the-air measurement results are presented and compared against reference measurements acquired using established conducted techniques. This paves the way for a redefined characterization workflow, in which the active RF circuitry of the phased array is first validated in a reverberation chamber and the radiation patterns are then validated in an anechoic chamber as a second step.

Bio: Teun van den Biggelaar received his MSc and PhD degree in Electrical Engineering (EE) with distinction from the Eindhoven University of Technology (TU/e), the Netherlands, in 2016 and 2020, respectively.
