Aftereffect in modified ionospheric plasma

Experimental and theoretical results of study of “aftereffect” phenomena arising in the modified ionosphere after the action of powerful radio emission are presented. The experimental results were obtained by the method of ionosphere sounding by short probing radio pulses. The theoretical model is based on the numerical solution of modified nonlinear Schrödinger equation with a driven extension. The qualitative agreement of theoretical and experimental results is obtained.
