Reflective intelligent surface with self-diagnosis capabilities and method for operating the same

Abstract

A reflective device includes an array of reflective elements under control of a control element, where each reflective element includes an antenna element configured to receive a radio-frequency (RF) signal incident on the reflective element. Each reflective element is operable in a functional operating state, in which the RF signal received by the antenna element of the reflective element is, at least partly, provided to be retransmitted by the antenna element of the reflective element. Each reflective element is operable in a diagnostic operating state, in which the RF signal received by the antenna element of the reflective element is, at least partly, provided as an RF signal usable for analysis purposes. The device and a method of using the device can be used to optimize states or decision making for a reflective device, and can also be used with artificial intelligence (AI) or machine learning (ML).
