Abstract
Disclosed is a phased array for steering an electromagnetic wave, which includes a first layer of active material, including parallel first inner and outer surfaces, and a second layer of active material, including parallel second inner and outer surfaces which are also parallel to the first inner and outer surfaces, the second layer being adjacent to the first layer. An electrically conductive ground plane of indium tin oxide is disposed between the first and second layers and in electrical contact with the first and second inner surfaces. A first series of spaced parallel electrodes, each of the electrodes being in the form of a thin strip of indium tin oxide, is deposited on the first outer surface, while a second series of spaced parallel electrodes, each of these electrodes also being in the form of a thin strip of indium tin oxide, is similarly deposited on the second outer surface but is orthogonal to the first series of electrodes. A first anti-reflective coating may be deposited on the first outer surface, with a second antireflective coating deposited on the second outer surface.
