Abstract

This article presents the development of a computer model for calculating the optical specifications of a liquid crystal modulator. It allows considering multipath interference in the device with acceptable approximations and does not require any significant computational costs. The performance analysis of a THz radiation modulator based on a multicellular liquid crystal structure is performed.
