Geometry-Informed Optimization of Binary RIS Configurations for Communication and Sensing
Angelos Gkekas, Alexandros I. Papadopoulos, Petros Andreas Pantazopoulos +3
Practical Reconfigurable Intelligent Surfaces (RISs) often support only a small number of phase states, making their configuration inherently discrete. For a 1-bit RIS with ele…
Physics-Aware RIS Codebook Compilation for Near-Field Beam Focusing under Mutual Coupling and Specular Reflections
Alexandros I. Papadopoulos, Maria Anna Pistela, Dimitrios Tyrovolas +5
Next-generation wireless networks are envisioned to achieve reliable, low-latency connectivity within environments characterized by strong multipath and severe channel variability.…
A Tutorial on Controlling Metasurfaces from the Network Perspective
Christos Liaskos, Evangelos Papapetrou, Kostas Katsalis +6
Metasurfaces have emerged as transformative electromagnetic structures for wireless communications, enabling the real-time control over wave propagation, yielding potential for imp…
