This thesis establishes a systematic hardware-oriented framework for wideband RIS design, high precision phase control, and spatial EM wave manipulation, providing experimentally validated solutions for next-generation wireless communication systems.

In this talk, I will first explain low-complexity, non-iterative, and near-optimal RIS (eflecting intelligent surface) joint active and passive beamformer designs for both narrowband and wideband assuming full channel information. Then, I will explain several practical channel estimation techniques for RIS systems. Lastly, I will introduce WiThRay, a versatile 3D wireless communication simulator based on ray-tracing developed by our lab, that can be used to evaluate different RIS techniques for various environments.
