1. A three-dimensional radio-frequency (RF) holographic transformer, comprising:

  • an array of elemental RF diffraction gratings, each of which comprises selected lengths of electrically conductive material and electrically insulating material arranged in a selected alternating sequence; and

    means for programming each of the elemental gratings independently, to vary the lengths of conductive and insulating material contained in each of the elemental gratings in order to achieve a desired effect on one or more RF beams incident on the away of gratings;

    wherein the array of gratings is programmable to perform different desired refractive operations on the incident RF beams, each such operation being performed independently of and simultaneously with the others.
