Abstract
A reflective device includes a control element and a reflective surface. The reflective surface includes a plurality of reflective elements, where each reflective element of the plurality 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 reflective surface with an adjustable phase shift. An operating frequency of the reflective surface is configurable by at least a subset of the plurality of reflective elements being divided into a number of sub-elements that are individually switched via the control element from an activated state, in which a respective sub-element contributes to the reflection of the incident RF signal, to a deactivated state, in which the respective sub-element does not contribute to the reflection of the incident RF signal, and vice-versa.
