Effects of Weakly Ionized Dusty Plasma on the Polarization Property of Obliquely Incident EM Waves

In this article, the effects of weakly ionized dusty plasma on the polarization property of obliquely incident EM waves are studied. Taking right-handed circularly polarized wave in x-band as an example, the polarization changes of EM waves passing through dusty and none dusty plasma are compared. And then the effects of the collision frequency and dust concentration of dusty plasma on the polarization state of EM waves are discussed. Numerical results indicate that the change of the polarization state of the EM waves is greatly affected by the dust concentration, and the change of the polarization state is closely related to the collision frequency.
