A new exact analytical dispersion relation for TM p-polarized millimeter nonlinear electromagnetic surface waves propagating along the interface of nonlinear ferromagnet cover and linear magnetic media has been derived theoretically. A nonlinear magnetic permeability of the cover can be considered as a function of the absolute value of the magnetic field of the wave and can be written as (mu) nl equals (mu) 1 + (mu) H, which is contacted with an isotropic linear dielectric substrate. The existence conditions for these waves to be propagated are studied. The power flow expressions versus the wave index have also been obtained. This new behavior could be used in Microwave Electronics and Integrated Circuits (IC) Technology.
