Patent ID: 7042618

Claim:
A circuit, comprising: a plurality of conductive structures arranged in a first plane; a contiguous conductive equipotential surface in a second plane parallel to said first plane; activation means configured to adjust an electric field between said first and second planes thereby activating one or more structures in said first plane by increasing a potential difference between said first and said second planes to a threshold level deemed to constitute an active state; and deactivation means configured to adjust said electric field between said first and second planes thereby deactivating one or more structures in said first plane by decreasing said potential difference between said first and said second planes below a threshold level deemed to constitute a deactivated state; wherein said activation of said one or more structures in said first plane results in a deformation of said second plane; and wherein said deformation of said second plane induces frustrating the total internal reflection (TIR) of light in a substrate of said first plane.
