Abstract
A spatial filtering surface includes a dielectric substrate and a plurality of spaced, resonant dipole elements positioned on the dielectric substrate. Each dipole element has dipole ends and an associated diode for controlling amplitude taper and a reflection phase of an electromagnetic field at a selected frequency with respect to an angle of incidence to the dielectric substrate. Bias lines interconnect the dipole elements for conducting a bias current to a dipole element.
