Abstract:
1. A method of achieving at least a partially opaque state in at least a region of a tunable frequency selective surface, the method comprising: applying a first voltage to alternating conductors disposed along a length of a first major surface and disposed at least partially within said region of the tunable frequency selective surface; applying the first voltage to alternating conductors disposed along a width of a second major surface and disposed at least partially within said region of the tunable frequency selective surface; applying a second voltage to remaining conductors disposed along the length of the first major surface and disposed at least partially within said region so as to cause a plurality of varactors coupling the conductors on the first major surface to be forward-biased; and applying a third voltage to remaining conductors disposed along the width of the second major surface and disposed at least partially within said region so as to cause a plurality of varactors coupling the conductors on the second major surface to be selectively forward or reverse biased.
