Abstract—The article studies the polarization of eigenwaves, the total microwave field, and magnetization in a ferromagnetic metal plate. Changes in the polarization and spatial distribution of the total field and magnetization are studied under ferromagnetic resonance and antiresonance conditions. It has been established that in the distribution of the amplitudes of the total microwave field and magnetization, there is both a contribution that decreases monotonically with depth and oscillations caused by spin wave interference. It is demonstrated that the wave interference is especially significant for weakly pinned spins at the film boundaries. It is established that oscillations of the angle of rotation of the polarization ellipse and ellipticity are large when the ferromagnetic antiresonance condition is satisfied.
