A Family of Hybrid Beyond-Diagonal RIS Architectures: Design and Performance Analysis
Konstantinos Ntougias, Ioannis Krikidis
Beyond-diagonal reconfigurable intelligent surfaces (BD-RISs) extend conventional diagonal RISs by allowing inter-element coupling, thereby enlarging the set of attainable scatteri…
Probabilistically Robust Optimization of IRS-aided SWIPT Under Coordinated Spectrum Underlay
Konstantinos Ntougias, Ioannis Krikidis
This study considers the Joint Transmit/Reflect Beamforming and Power Splitting (JTRBPS) optimization problem in a spectrum underlay setting, such that the transmit sum-energy of t…
Simultaneous Wireless Information and Power Transfer for Federated Learning
José Mairton B. da Silva, Konstantinos Ntougias, Ioannis Krikidis +2
In the Internet of Things, learning is one of most prominent tasks. In this paper, we consider an Internet of Things scenario where federated learning is used with simultaneous tra…
