The purpose is a research using mathematical modeling at electrodynamic accuracy level of dynamic modes and volume or surface magneto static modes propagating in multilayer ferrite-dielectric waveguides with finite width. Results of simulating of eigen electromagnetic and volume or surface magneto static waves in shielded 2D ferrite layers structures with tangent biasing magnetic field are done. Propagation constants frequency dependencies of dynamic and magneto static modes in these gyrotropic waveguides were calculated by the multimode autonomous blocks method. The change of dynamic and magneto static modes existence frequency regions near longitudinal or transverse ferromagnetic resonance frequencies are researched. Numerical analysis of cut-off frequencies of depth, width volume and width surface magneto static modes in 2D ferrite waveguiding structures with the tangent biasing magnetic field is carried out. Theoretical method for determining of existence frequency regions of the width volume or surface magneto static modes at the 3D waves number space using MSW dispersion surfaces is proposed.
