Non-Reciprocal Dynamic Metasurface Antenna: Practical Multiport-Network Modeling and Optimization for Multi-User Interference Resilience
Shuai S. A. Yuan, Jean Tapie, Bahman Amrahi +2
Channel reciprocity fundamentally limits full-duplex (FD) base stations due to multi-user co-channel interference. We examine the potential of deploying a non-reciprocal dynamic me…
Optimizing Dynamic Metasurface Antenna Configurations for Direction-of-Arrival and Polarization Estimation Using an Experimentally Calibrated Multiport-Network Model
Jean Tapie, Philipp del Hougne
Sensing the direction of arrival and polarization of impinging signals is a key prerequisite for beamforming and interference mitigation in modern wireless communication systems. D…
Channel Estimation via Tensor Decomposition for Dynamic Metasurface Antennas with Known Mutual Coupling: Algorithms and Experiments
Jean Tapie, Bruno Sokal, André L. F. de Almeida +1
Dynamic metasurface antennas (DMAs) are an emerging hybrid-MIMO technology distinguished by an ultrathin form factor, low cost, and low power consumption. In real-world DMA prototy…
End-to-End Dynamic Metasurface Antenna Wireless System: Prototype, Opportunities, and Challenges
François Yven, Jean Tapie, Jérôme Sol +1
Dynamic metasurface antennas (DMAs) are a promising hybrid analog/digital beamforming technology to realize next-generation wireless systems with low cost, footprint, and power con…
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.…
