RF-Fencing: A Novel RIS-Based Service for Proactive Covert Communications
Alexandros I. Papadopoulos, Dimitrios Tyrovolas, Alexandros Pitilakis +6
Programmable wireless environments (PWEs), empowered by reconfigurable intelligent surfaces (RISes), have emerged as a transformative paradigm for next-generation networks, enablin…
Analysis and Design of a Reconfigurable Metasurface based on Chalcogenide Phase-Change Material for Operation in the Near and Mid Infrared
Alexandros Pitilakis, Alexandros Katsios, Alexandros-Apostolos A. Boulogeorgos
We analyze, design and assess the performance of a reflective reconfigurable metasurface (MS) architecture for optical wireless communications. The device is based on the Ge-Sb-Te…
Equivalent Circuit Modeling of a Lumped-element Loaded Metasurface under Arbitrary Incidence and Polarization
Athanasios Nousiou, Christos K. Liaskos, Nikolaos V. Kantartzis +1
In this work we develop a simple equivalent circuit model (ECM) that predicts the spectral response of a lumped-element loaded single patterned layer reflective metasurface. The pr…
Dynamic Programmable Wireless Environment with UAV-mounted Static Metasurfaces
Prodromos-Vasileios Mekikis, Dimitrios Tyrovolas, Sotiris Tegos +8
Reconfigurable intelligent surfaces (RISs) are artificial planar structures able to offer a unique way of manipulating propagated wireless signals. Commonly composed of a number of…
XR-RF Imaging Enabled by Software-Defined Metasurfaces and Machine Learning: Foundational Vision, Technologies and Challenges
C. Liaskos, A. Tsioliaridou, K. Georgopoulos +18
We present a new approach to Extended Reality (XR), denoted as iCOPYWAVES, which seeks to offer naturally low-latency operation and cost-effectiveness, overcoming the critical scal…
Multi-functional metasurface architecture for amplitude, polarization and wavefront control
A. Pitilakis, M. Seckel, A. C. Tasolamprou +10
Metasurfaces (MSs) have been utilized to manipulate different properties of electromagnetic waves. By combining local control over the wave amplitude, phase, and polarization into…
