BIOS: An Omni RIS for Independent Reflection and Refraction Beamforming
IEEE Wireless Communications Letters（2022）
摘要
As an important member of reconfigurable intelligent surfaces (RISs), intelligent omni-surface (IOS) has attracted increasing attention recently due to its ability of simultaneously serving user equipments (UEs) on both sides of the metasurface. However, in practical implementation, the phase shifts of the IOS must be shared for both reflection and refraction signals, which inevitably leads to cou...
