摘要：

Superheterodyne amplification of sub-millimeter electromagnetic waves in GasAs due to negative differential mobility is analyzed. The nonlinearity arises from the current and the magnetic field of the electromagnetic waves. The case of interaction of two traveling counter propagating electromagnetic waves and the following space charge wave in a n-GaAs film placed onto i-GaAs substrate is considered. The case of 2D electron gas is also analyzed The simulation of this nonlinear interaction shows a certain increment of the amplification.
