Next-generation 6G wireless communication systems are anticipated to bring ultra-high speed, ultra-high reliability, and ultra-low delay global coverage. For wireless communication technologies deployed to date, the radio-frequency (RF) signal propagation environment has been treated as a fixed constraint and limitation, under which theories are developed, standards are written, and devices are designed and developed. Recently, reconfigurable intelligent surface (RIS) has emerged as an enabling technology to overcome these limitations by proactively controlling and optimizing the RF signal propagation environment for future 6G wireless communications. Installed on building facades or billboards, these large planar electromagnetic RIS structures can redirect signals between wireless access points and user devices, overcoming adverse effects caused by signal blockage. They help improve coverage, suppress interference, and enhance security. However, the state-of-the-art RIS designs still face the challenge of providing true full-space coverage and leave some areas with poor signal quality or no signal at all. This project aims to realize a novel RIS technology capable of achieving true full-space coverage by transmitting, reflecting, and scattering electromagnetic waves carrying wireless signals to any possible direction in 3-D space. In addition, simultaneous signal reception and wireless power transfer will be studied. The success of this project will bring the envisioned next
