Abstract
Novel mechanism of suppression losses in plasmonic subsystem in metals and semiconductors is suggested. If two parametrically coupled fields are applied to a metal plasma, a non-linearity of the transport equation affects the electric response, or the permittivity. If the coupling constant between the probe wave and the support wave is small, the permittivity, at the frequency of the probe wave, is still Drude-like, with the re-normalized plasmon frequency. In the case of a strong coupling, unusual response effects are possible (the induced transparency and the considerable suppression of the plasmon losses), with profoundly non-Drude permittivity function.
