- Abstract
We study a method for increasing the efficiency of penetration of an intense electromagnetic wave into a layer of dense plasma. The method is based on the phenomenon of spatio-temporal synchronism of the nonlinear dynamic structures, which are excited in the layer, with the modulated wave incident on the layer. It has been established that in the case of a relatively weakly overdense plasma, the efficiency of constant-amplitude wave penetration into the plasma layer is determined by a single nonlinear parameter, namely, the ratio of the intensity of the incident radiation to the degree of plasma super-criticality, and increases with an increase in this parameter. It is found that a modulation of the amplitude of an incident wave, whose period is a multiple of the soliton generation period, can lead to a significant increase in the penetration efficiency.
