Simulation of Dynamic Spectra of Type III Radio Waves In the Presence of Collisional Damping of Langmuir Waves
Abstract
Using of simulation of quasilinear equations, generation of Langmuir waves and velocity of beam propagation in the presence of collisional damping of Langmuir waves are investigated. It is shown that in the presence of collisional damping, the level of Langmuir waves decreases. The average velocity of beam propagation is constant during the course of propagation and its value is larger than that of collision-less case. Dynamic spectra of type III radio waves for fundamental and harmonic emissions is simulated and it is shown that in the presence collisional damping the level of type III radio waves decreases.
