Demo: Demonstration of Reconfigurable Intelligent Surface (RIS)-assisted Simultaneous Wireless Information and Power Transfer (SWIPT)

Abstract

Recently, reconfigurable intelligent surface (RIS) rises as one of the potential key technologies for the next generation of wireless communications. RIS consists of a large array of planar elements, each of which can be configured individually to induce additional phase shifts to the impinging signals. Therefore, the wireless propagation can be handled in a smart manner by reconfiguring the RIS. In this article, we demonstrate an RIS-assisted simultaneous wireless information and power transfer (SWIPT) system for the Internet of Things (IoT) devices. The experiment results of the RIS-assisted SWIPT system show promising gains in the wireless transmission quality over the SWIPT system without RIS deployment.
