Summary:The polarization of eigenwaves and the total microwave magnetic field and microwave magnetization in a ferromagnetic metal plate is considered. It is established that, in the case of a thin plate with a thickness less than the skin depth, a significant role is played by the interference of the forward and backward eigenwaves. It is shown that both the microwave magnetization and the microwave magnetic field are elliptically polarized and the lengths of the semi-axes of the ellipses and their inclination, as well as the directions of the rotation of the corresponding vectors, are determined by the magnetization field. In particular, it is established that the polarization of the microwave field is different under the ferromagnetic resonance and ferromagnetic antiresonance conditions.
