A system, in a programmable active reflector (AR) device associated with a first radio frequency (RF) device and a second RF device, receives a request and associated metadata from the second RF device via a first antenna array. Based on the received request and associated metadata, one or more antenna control signals are received from the first RF device. The programmable AR device is dynamically selected and controlled by the first RF device based on a set of criteria. A controlled plurality of RF signals is transmitted, via a second antenna array, to the second RF device within a transmission range of the programmable AR device based on the associated metadata. The controlled plurality of RF signals are cancelled at the second RF device based on the associated metadata.

The sub-reflector comprising a plurality of actuators disposed over and attached to its outer face. Each of the actuators is adapted to locally deform the surface of the sub-reflector adjacent to that actuator in response to a change in the actuator position.

Disclosed are devices and methods for selecting, at an antenna reflector, electromagnetic waves with a certain polarization and frequency and rejecting electromagnetic waves with different polarizations and/or frequencies. In one aspect, a directional antenna includes a shaped reflector surface with a series of conforming layers attached to the surface. The layers include a reflecting layer that causes reflection of electromagnetic waves at a specific frequency and polarization. Underneath the reflecting layer is a frequency selective surface (FSS) layer that absorbs electromagnetic waves not at the specific frequency or polarization which pass through the reflecting layer. Underneath the absorbing layer is a conductive layer.
