EM inverse scattering analysis of plasma frequency and electron collision frequency based on genetic algorithm

An one-dimensional plasma frequency and the electron collision frequency distribution inversion method is proposed, which combined the current density Laplace transform finite difference time domain division method and the genetic algorithm. Based on the calculation results of one-dimensional FDTD electromagnetic scattering, the spatial distribution of plasma frequency and electron collision frequency of plasma generated by a plasma generator are reversed. The complex relationship between the time and space cost and the calculated parameters are analyzed. The numerical results show that this method is correct, simple and easy to be parallel.
