摘要

本文研究了电磁波在平面屏蔽介质波导中的传播问题。该波导具有各向同性的非均匀介电常数和恒定的磁导率。考虑对称导波的特征是一对(耦合)传播常数。将物理问题简化为算子铅笔的特征值问题。证明了所求特征值的离散性。

Symmetric guided waves in an isotropic inhomogeneous shielded waveguide

The paper treats a problem of propagation of electromagnetic wave in a plane shielded dielectric waveguide. The waveguide is characterised by an isotropic inhomogeneous permittivity and constant permeability. Considered symmetric guided waves are characterized by a pair of (coupled) propagation constants. The physical problem is reduced to an eigenvalue problem for an operator pencil. A discreteness property for the sought eigenvalues is proved.
