Abstract

A wavefront phase modulator device utilizes a dielectric reflector affixed to a substrate. Overlapping the dielectric reflector is a transmissive deformable media layer possessing rubbery attributes. Affixed to the surface of the layer which is opposite to the substrate is a transmissive deformable conductor. Affixing reflectors to the substrate avoids compromises associated with deformable reflectors affixed to deformable media, thereby enhancing reflectivity. Furthermore, affixing a deformable transmissive conductor to the surface of the transmissive deformable layer which opposes the substrate eliminates extraneous components, such as a second substrate, and/or gaps. An electron beam addressing technique is described that enables electric fields to be established in the media layer to establish electrostatic forces on the conductor which leads to deformations in the conductor and the deformable layer thereby phase modulating a wavefront which is incident on the conductor and traverses the layer in accordance with an information bearing signal.
