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…
Beyond-Diagonal RIS Prototype and Performance Evaluation
Jean Tapie, Matteo Nerini, Bruno Clerckx +1
We present the first experimental prototype of a reflective beyond-diagonal reconfigurable intelligent surface (BD-RIS), i.e., a RIS with reconfigurable inter-element connections.…
T-Parameters Based Modeling for Stacked Intelligent Metasurfaces: Tractable and Physically Consistent Model
Hamad Yahya, Matteo Nerini, Bruno Clerckx +1
This work develops a physically consistent model for stacked intelligent metasurfaces (SIM) using multiport network theory and transfer scattering parameters (T-parameters). Unlike…
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…
