1. An active redirection system, comprising:
a redirection device of reflective elements having sizes, shapes and configurations configured to generate a first phase distribution across the redirection device, the first phase distribution having a first reflection direction;
a control module coupled to the redirection device and adapted to provide energy to one or more reflective elements to generate a second phase distribution across the redirection device, the second phase distribution having a second reflection direction; and
a plurality of passive redirection devices each having a respective reflection phase, wherein the plurality of passive redirection devices are configured to generate a plurality of RF beams,
wherein the active redirection system is configured for reflecting millimeter wave signals.
