On the theory of radiation properties of an accelerated supersonic soliton

Taking into account the relativistic effect of a transverse high-frequency electromagnetic wave on the plasma electrons, the radiation properties of an accelerated supersonic soliton is studied, in the case when the acceleration of the soliton is due to an inhomogeneous density barrier of a wide range of applications. It is shown that the accelerated supersonic soliton radiates an ion-sound wave. The basic equations describing the dynamic behaviour of the high-frequency electromagnetic waves, as well as the emission of the ion-sound waves are formulated. The distribution of the perturbed concentration in the ion-sound wave is derived. The energy flux of the soliton + ion-sound system is estimated.
