Interference bleaching and absorption in magnetic films under oblique incidence of counterpropagating waves

The interference control of absorbance and transmittance of a thin magnetic layer using variations in (i) phase difference of counterpropagating coherent waves that are incident at a certain angle on opposite sides of the layer and (ii) external magnetic field is studied. It is demonstrated that the absorbance depends on the parameters of the layer. Almost total absorption and dissipation-free transmission of energy are possible for the absorbing layer.
