Abstract
A controllable frequency selective surface. The frequency selective surface has a plurality of conductive patches with integrated circuits straddling gaps between, and connected to, pairs of patches separated by gaps. Each integrated circuit presents a controllable impedance and as a result the characteristics of the frequency selective surface are controllable.
