Absorptivity control of magnetic film by interference of counter propagating waves

Abstract

We investigate the ability of interference absorption control in thin magnetic films. This control is obtained by variation of external magnetic field and phase difference of counter propagating waves. Depending upon this parameters, ferromagnetic film can be observed as material with low and high level of absorption. Thus, when the radiation passes through the magnetic layer there are possible both the total absorption energy and the process without energy dissipations.
