This talk presents an investigation of electromagnetic wave propagation through
magnetic multilayers and superlattices based on the propagation matrix P of a
magnetic film.  By using this matrix P, we obtained the transmission and
reflection coefficients of layered magnetic media, including semi-infinite
magnetic surfaces, magnetic multilayers and semi-infinite magnetic
superlattices.  The numerical results show that the EM modes of a magnetic
layer system are excited and manifested as the sharp dips in the S-polarized
reflection.  The analytic dispersion relations of magnetic polaritons for
arbitary magnetic multilayers systems are represented by the matrix P.
