Abstract

The nonlinear interaction of a dc current flowing in a thin metal film with an electromagnetic wave illuminating the sample in a symmetric manner with respect to the magnetic field is investigated theoretically. The nonlinearity is due to the most typical mechanism for pure metals at low temperatures - the magnetodynamic mechanism, involving the effect of the magnetic field of the current and wave field on the electron trajectories. It is shown that this interaction leads to sharp kinks in the time dependence of the electric field of the wave at the surface of the samole and to a peculiar electromagnetic sienal amplification effect.
