Polarization-Aware Rotatable Antennas for RIS-Empowered Symbiotic Radios
Chao Zhang, Ruizhe Long, Boon-Hee Soong +1
This paper investigates a dual-polarized reconfigurable intelligent surface (DP-RIS)-empowered symbiotic radio (SR) system with rotatable antennas (RAs). By reconfiguring antenna o…
Simultaneous Indoor and Outdoor Coverage with Conformal Intelligent Omni-Surface
Yiqi Chen, Xiaoming She, Jianchi Zhu +3
Seamless indoor--outdoor coverage conventionally relies on coordinated outdoor macro cells and indoor small cells, incurring high deployment and backhaul costs. Intelligent omni-su…
