Antenna Coding Empowered by Pixel Antennas
Shanpu Shen, Kai-Kit Wong, Ross Murch
Pixel antennas, based on discretizing a continuous radiation surface into small elements called pixels, are a flexible reconfigurable antenna technology. By controlling the connect…
Beyond Diagonal Reconfigurable Intelligent Surfaces in Wideband OFDM Communications: Circuit-Based Modeling and Optimization
Hongyu Li, Matteo Nerini, Shanpu Shen +1
This work investigates the modeling and optimization of beyond diagonal reconfigurable intelligent surface (BD-RIS), which generalizes conventional RIS with diagonal phase shift ma…
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…
Channel Estimation and Beamforming for Beyond Diagonal Reconfigurable Intelligent Surfaces
Hongyu Li, Shanpu Shen, Yumeng Zhang +1
Beyond diagonal reconfigurable intelligent surface (BD-RIS) is a new advance and generalization of the RIS technique. BD-RIS breaks through the isolation between RIS elements by cr…
Static Grouping Strategy Design for Beyond Diagonal Reconfigurable Intelligent Surfaces
Matteo Nerini, Shanpu Shen, Bruno Clerckx
