Electromagnetic Waves in Anisotropic Multilayer Ferrite Structures with Trigonal Symmetry under Parallel Magnetization

Abstract

The dispersion relations of retarded modes in recurrent form and the energy flux distribution for waves propagating in multilayer ferrite‐dielectric structures magnetized in the plane are obtained by using an impedance matching technique. The structures examined are arbitrary combinations of dielectric layers and (111)‐oriented ferrite films with basic cubic anisotropy. The applied bias magnetic field is assumed to be directed along the 〈110〉 ferrite film axis. The waves propagating perpendicular to the applied field direction are considered. The permeability tensor of a layer with trigonal symmetry is obtained to describe the dynamic magnetic properties of the ferrite layers. As examples of the described algorithm numerical calculations for some structures are carried out.
