The amplification of a surface electromagnetic wave by means ofultrarelativistic monoenergetic electron bunch running over the flat plasmasurface in absence of a magnetic field is studied theoretically. It is shownthat when the ratio of electron bunch number density to plasma electron numberdensity multiplied by a powered to 5 relativity factor is much higher than 1,i.e $\gamma^5 n_b/n_p>> 1$, the saturation field of the surface electromagneticwave induced by trapping of bunch electrons gains the magnitude:$E_x=B_y\approx 0.16 \frac{\omega_p m c}{e} (\frac{2n_b}{\gamma^2 n_p})^{1/7}$and does not approache the surface electromagnetic wave front breakdownthreshold in plasma. The surface electromagnetic wave saturation energy densityin plasma can exceed the electron bunch energy density. Here, we discuss thepossibility of generation of superpower Teraherz radiation on a basis of suchscheme.
