Electrodynamic Models of Structures with Distributed Interaction of Waves of Different Physical Nature

摘要

An electrodynamic theory of anisotropic waveguiding structures (WSs) containing active polarized medium layers and guiding certain types of slow wave processes is developed. Unlike well-known concepts, the theory describes electromagnetic processes in the presence of a distributed interaction of waves differing in nature and enables one to consider a variety of physical effects determined both by the WS geometry (depending on frequency) and parameters of external (electric and magnetic) fields. Numerical electrodynamic analysis is performed taking into account the nonelectromagnetic component of the eigenmode spectrum for WSs containing in-plane magnetized ferrite layers. Interaction between electromagnetic waves and magnetostatic bulk and surface waves in shielded multilayer ferrite-dielectric WSs is simulated.
