Modal liquid-crystal wavefront corrector on a ceramic substrate: the single-contact approximation

The possibility of manufacturing a multichannel modal liquid-crystal corrector of a new type based on a ceramic substrate with a high permittivity is confirmed theoretically and experimentally. A mathematical model of the single-electrode corrector is proposed and used to study the dependences of the voltage and phase profiles on the properties of the corrector design. The technology of manufacturing a ceramic substrate with built-in electrodes is developed.
