Electromagnetic Modeling of Deformation-Based Pinching Antennas
Dimitrios Tyrovolas, Nikos C. Sagias, Ke Guan +2
Pinching-antenna systems (PAS) rely on local perturbations of a guiding structure to radiate part of the guided electromagnetic energy, making the physical response of the resultin…
Curved Waveguide-Enabled Pinching-Antenna System (C-PAS): Communication Performance Analysis
Yayun Qu, Kunrui Cao, Tao Wang +5
Existing studies on the pinching-antenna system (PAS) assume that waveguides are deployed straight, which fails to serve communication regions with curved boundaries. To address th…
Vertical Pinching Antenna Systems (V-PAS) Aided UAV Communications
Tao Wang, Kunrui Cao, Yayun Qu +4
To address the limitation that existing horizontal pinching antenna systems (PAS) are primarily designed for ground users and confined to two-dimensional (2D) coverage, this paper…
SCROOGE: A Physics-Aware Framework for Efficient Orchestration of RIS-Assisted Networks
Alexandros I. Papadopoulos, Sotiris Kopsinos, Dimitrios Tyrovolas +4
Reconfigurable Intelligent Surfaces (RISs) are emerging as a key enabler of Programmable Wireless Environments for 6G, but their practical integration into operational networks sti…
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…
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.…
Constellation Design for Robust Interference Mitigation
Athanasios T. Papadopoulos, Thrassos K. Oikonomou, Dimitrios Tyrovolas +4
This paper investigates symbol detection for single-carrier communication systems operating in the presence of additive interference with Nakagami-m statistics. Such interference d…
Constellation Design and Detection under Generalized Hardware Impairments
Thrassos K. Oikonomou, Dimitrios Tyrovolas, Sotiris A. Tegos +3
This paper presents a maximum-likelihood detection framework that jointly mitigates hardware (HW) impairments in both amplitude and phase. By modeling transceiver distortions as re…
RIS-Assisted 3D Spherical Splatting for Object Composition Visualization using Detection Transformers
Anastasios T. Sotiropoulos, Stavros Tsimpoukis, Dimitrios Tyrovolas +4
The pursuit of immersive and structurally aware multimedia experiences has intensified interest in sensing modalities that reconstruct objects beyond the limits of visible light. C…
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…
