Abstract: Linear and nonlinear stages of a dissipative instability that arises in an electron flow above a resistive metal surface, have been studied in the framework of a quasi-optical approach with the Leontovich impedance boundary conditions. It is shown that this instability can be used for the amplification of short-wavelength radiation including that in the terahertz frequency range.
