The problem on normal waves in an open regular waveguide of arbitrary cross-section is considered. The permittivity and permeability of the waveguide are described by tensors. The determination of normal waves is reduced to a boundary eigenvalue problem for longitudinal components of the electromagnetic field in Sobolev spaces. A variational formulation corresponding to this problem is obtained. The variational relation leads to an eigenvalue problem for the operator-function. Properties of the operator-function are investigated. Discreteness of the spectrum is proved. Numerical results are presented. [ABSTRACT FROM AUTHOR] |
