Abstract :
In this work we investigate WFR of SMSW propagating in a ferromagnetic film metallized from one side. The dispersion relation in this case is nonreciprocal. Here k > 0 corresponds to the surface wave, propagating near the metallized surface of the ferromagnetic film, and k < 0 - to the wave, localized near the free surface, deltaomegak describes frequency difference of waves, propagating in opposite directions (+k and -k), and is given by deltaomegak = omegaM(1-exp(-2|k|d))/4.
