Fraunhofer Diffraction by Slit Into a Homogeneous Anisotropic Medium with an Open Surface of Wave Vectors

Abstract

Fraunhofer diffraction of an electromagnetic wave by a slit on an opaque screen located between a vacuum and an anisotropic medium with an open wave vector surface (WVS) is considered. A formula for diffraction in a material medium is obtained, including the case of diffraction into a uniaxial anisotropic medium in the absence of absorption, and diffraction minima and maxima formation is studied.
