Abstract

The multi-parameter optimization of plasma was performed by using the Nelder-Mead algorithm for getting the optimal point, and the optimal solution of plasma's parameters in stealth application was solved. The results of the parametric inversion show that in the spans of the parameters against the nonmagnetic and uniform plasma, the attenuation level was decided by the electron density, collision frequency and the thickness of plasma layer. The optimal absorptive wavelength was decided by the thickness of the plasma layer, and when the frequency of the incident wave was greater than a threshold, the collision frequency of plasma was tended towards a stable value.
