Abstract: In this invention submission the foundations for the creation of an analogue computational device are disclosed. The computational device consists of an array of individually controlled pixels, capable of altering their dielectric characteristics under the influence of an external dc electric field. Upon illumination by an incident wavefront, such a surface is capable of altering its dielectric characteristics to perform mathematical operations directly on an incident signal. An example of such a surface is given in Fig.1, together with the detail of the individual pixel.
(a) perspective view showing all layers, (b) perspective view showing individual layers in detail, (c) plate waveguide (PPWG) composite structure composed of dielectrics and thin (sub-skin depth) phase change material, such as VOx (active material)
