Reconfigurable digital metasurface for 3-bit phase encoding

In this contribution, we propose, design, simulate and prototypically realize a 3-bit digital coding metasurface by controlling the phase and amplitude response of the metasurface, which is applicable to a wireless telecommunication system as a transmitter. The proposed metasurface consists of metal patches on a dielectric substrate and varactors, which allow controlling the phase and amplitude of the metasurface’s reﬂected wave by the varactors’ bias voltages.
