Abstract
A metasurface design is presented, where its meta-atoms are populated with programmable integrated circuits. The programmable integrated circuit loads the meta-atom with four complex impedance loading elements. This grants the meta-atom the capability to programmatically set its reflection amplitude and phase for both transverse electric and transverse magnetic polarizations. With this ability, multiple pencil beam patterns have been demonstrated, where each pencil beam's polarization can be programmatically set between linear, circular, or even elliptic polarization. The presented design operates in the vicinity of 3.6 GHz, and therefore has the potential to be incorporated into multiple-user mobile communication systems, including 5G networks and future wireless telecommunication networks.
