Movable Signals with Dual-Polarized Fixed Intelligent Surfaces: Beyond Diagonal Reflection Matrices
Matteo Nerini, Bruno Clerckx
This paper investigates wireless systems aided by dual-polarized intelligent surfaces. We compare reconfigurable intelligent surface (RIS), which adjust their reflection matrices,…
Capacity of MIMO Systems Aided by Microwave Linear Analog Computers (MiLACs)
Matteo Nerini, Bruno Clerckx
Future wireless systems, known as gigantic multiple-input multiple-output (MIMO), are expected to enhance performance by significantly increasing the number of antennas, e.g., a fe…
Wideband Modeling and Beamforming for Beyond Diagonal Reconfigurable Intelligent Surfaces
Hongyu Li, Matteo Nerini, Shanpu Shen +1
This work studies the wideband modeling and beamforming design of beyond diagonal reconfigurable intelligent surface (BD-RIS), which generalizes and goes beyond conventional RIS wi…
Static Grouping Strategy Design for Beyond Diagonal Reconfigurable Intelligent Surfaces
Matteo Nerini, Shanpu Shen, Bruno Clerckx
Beyond diagonal reconfigurable intelligent surface (BD-RIS) extends conventional RIS through novel architectures, such as group-connected RIS, with scattering matrix not restricted…
