Abstract

Surface magnetic microwave polaritons of finite amplitude propagating along the interface between ferrite and nonlinear dielectric, located in external weakly non-uniform wall-like magnetic field, are theoretically investigated. The analysis is based on application of variational method added with bilinear relation like Lorenz lemma. It was shown that the wave dispersion and transverse wave profile along field non-uniformity essentially depend on wave amplitude
