Eigen electromagnetics wave in round waveguide with biisotropic mode

The general method for determination of the structure of fields and integrated characteristics consists of construction of Maxwell equations for a boundless biisotropic environment on the basis of which, in view of the boundary conditions, is formed an eigenvalue equation. We describe an alternative approach consisting of the numerical integration of a system of wave equations with given boundary conditions. This permits us to expand the class of soluble problems and to consider waveguides of continually non-uniform structure with biisotropic cross section by filling.
