Abstract
A reflective device includes a control element and an array of reflective elements. Each reflective element of the array of reflective elements has an antenna element and a phase shifter and is under control of the control element so as to reflect a radio-frequency (RF) signal incident on the each reflective element with an adjustable phase shift, where different phase shifts are realized by the phase shifter channeling the RF signal into a specific one of a number of different delay lines. Each of the different delay lines includes an extension unit configured to extract a portion of a power of the RF signal channeled into the respective specific one delay line by the phase shifter and to measure or estimate the voltage, the current and/or the power of the extracted portion of the RF signal.
