The high-frequency spatial dispersion of conductivity of electrons in the 2D-system was analyzed. The effects of the stationary electric field on the high-frequency electron dynamics were taken into account, which allowed revealing in the ballistic approximation: a strong effect of non-reciprocity, oscillatory behavior, and the presence of frequency regions with negative values of the actual conductivity. This allowed us to show that in the considered system there may be an increase in THz radiation in the frequency range of 3-4 THz. This conclusion is confirmed by the calculation of eigenfrequencies and decrements/increments of plasmonic modes.
