Abstract
A reflective device includes a control element, and a reflective surface with a plurality of reflective elements. Each reflective element of the plurality of reflective elements includes an antenna element and a phase shifting arrangement 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. The plurality of reflective elements are connected to the control element via a cell selection bus system that interconnects the plurality of reflective elements.
