Abstract: The present technology pertains to a system and method of operation of a metamaterial phase shifter having various use applications. In one aspect of the present disclosure, a phase shifter includes a network of tunable impedance elements and a controller. The controller is coupled to the network of tunable impedance elements and configured to receive a phase shift input value and determine a corresponding tuning voltage to be supplied to each tunable impedance element of the network of tunable impedance elements based on the phase shift input value, the network of tunable impedance element being configured to shift a phase of an input signal based on tuning voltages supplied to the network of tunable impedance elements by the controller.
