Study on Attenuation Characteristics of THz Waves in Dusty Plasma with Full Ionization under Multi-angle and Multi-magnetic fields

The function of the electron can be solved by Boltzmann equation and the Fokker–Planck Landau (FPL) model. The complex permittivity of THz waves is got by solving electron disturbance distribution function in the dusty plasma with full ionization. The corresponding attenuation coefficient is obtained by Wentzel–Kramers–Brillouin (WKB) method. The incidence angle and magnetic field are the main research objects to analyze the attenuation characteristics (ATTC) of electromagnetic (EM) wave. In addition, the effect of effective collision frequency on the ATTC of THz waves is also studied. Each calculation factor has 6 calculation results, which can be used to get the corresponding change law. The results show that the ATTC of THz waves can be affected to a certain extent. These results provide a good theoretical and technical support for solving related problems such as interference of EM wave communication by dusty plasma.
