The linear wire in anisotropic medium

Abstract

In the framework of a method of integral equations of macroscopic electromagnetics it is shown, that with any orientation of the wire the electromagnetic field in far zone represents two waves-ordinary and unordinary. In that specific case for wire located parallel to axis of anisotropy, the electromagnetic field is characterised only by an unordinary wave. With symmetric excitation of the wire the power pattern in a plane, perpendicular to axis of the wire, as well as in isotropic medium, represents a circle, which radius is defined by length of the wire and equivalent permittivity.
