Study on Propagation Characteristics of Electromagnetic Wave with Oblique Incident in Fully Ionized Dusty Plasma

Abstract

Based on Bhatnagar-Gross-Krook (BGK) collision model and general dusty plasma motion theory, the dielectric constant of fully ionized dusty plasma is calculated. In this paper, Wentzel-Kramers-Brillouin (WKB) method is used to calculate the influence of dusty plasma's thickness and effective collision frequency on electromagnetic wave propagation characteristics at different incident angles. The results show that the attenuation coefficient $(\alpha)$ increases with the increase of incident angle, dusty plasma's thickness and effective collision frequency for certain circularly polarized waves. These results provide theoretical guidance for studying the interaction between electromagnetic wave and dusty plasma.
