1. An electromagnetic radiation signal switch comprising:

  • (a) a plurality of radiation input ports for receiving a plurality of radiation input signals, and a plurality of radiation output ports for collecting a plurality of output radiation signals;

    (b) a first sheet made of substantially transparent material, and a second sheet which is disposed substantially parallel to said first sheet;

    (c) a monolayer of rotatable elements, each of which comprises an embedded reflector, and an embedded electric dipole in said element;

    (d) wherein each said reflector is disposed in a cellular structure positioned between said first and second sheets;

    (e) wherein each said reflector is individually and independently rotatable about at least one of two orthogonal axes;

    (f) wherein a transparent ground-plane electrode layer is provided on a surface of said first sheet, and a resistive electrical grid layer is provided on a surface of said second sheet to cooperatively produce an arrangement of temporally and spatially varying electric fields for orienting said bipolar reflectors about each of the aforesaid two axes; and

    (g) said rotatable reflectors substantially reflecting at least a portion of said optical inputs.
