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…
Experimental Multiport-Network Parameter Estimation for a Dynamic Metasurface Antenna
Jean Tapie, Philipp del Hougne
Most use cases of reconfigurable antennas require an accurate forward model mapping configuration to radiated field (and reflections at feeds). Emerging dynamic metasurface antenna…
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.…
Scalable Multiport Antenna Array Characterization with PCB-Realized Tunable Load Network Providing Additional "Virtual" VNA Ports
Jean Tapie, Philipp del Hougne
We prototype a PCB-realized tunable load network whose ports serve as additional "virtual" VNA ports in a "Virtual VNA" measurement setup. The latter enables the estimation of a ma…
Benefits of Mutual Coupling in Dynamic Metasurface Antennas
Hugo Prod'homme, Jean Tapie, Luc Le Magoarou +1
Dynamic metasurface antennas (DMAs) are a promising embodiment of next-generation reconfigurable antenna technology to realize base stations and access points with reduced cost and…
Systematic Physics-Compliant Analysis of Over-the-Air Channel Equalization in RIS-Parametrized Wireless Networks-on-Chip
Jean Tapie, Hugo Prod'homme, Mohammadreza F. Imani +1
Wireless networks-on-chip (WNoCs) are an enticing complementary interconnect technology for multi-core chips but face severe resource constraints. Being limited to simple on-off-ke…
