Programmable Metasurface Transmitter Aided Multicast Systems

2020 IEEE Wireless Communications and Networking Conference (WCNC), 2020
This paper considers a multi-antenna multicast system with programmable metasurface (PMS) based transmitter. Taking into account of the finite-resolution phase shifts of PMSs, a novel beam training approach is proposed, which achieves comparable performance as the exhaustive beam searching method but with much lower time overhead.

Optically-Driven Programmable Microwave Metasurfaces

2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC), 2020
Programmable metasurfaces have the real-time programmability for controlling electromagnetic (EM) waves, possessing many potential applications. Programmable metasurfaces were constructed typically by using the direct-current (DC) control system. However, these electronically-controlled metasurfaces need field-programmable gate arrays, power supplies ...

Programmable metasurface for radiation beam control

This dissertation focuses on the design, development, and experiment of a programmable metasurface-based reconfigurable reflectarray (R-RA) system, featuring dual polarizations and 1-bit phase shift resolution. The proposed R-RA unit cell incorporates PIN diodes to dynamically control the reflection phase of incident waves, enabling real-time beam ...
