Faraday Angle of Linearly Polarized Waves Along Magnetic Field in Magnetized Collisional Plasmas

In magnetized collisional plasmas, owing to the differences between attenuations ofleft- and right-handed polarized waves, the Faraday rotation angle differs from that in collisionalessplasmas. In this paper, the attenuation rates of left- and right-handed polarized waves areanalyzed, and the Faraday angle is expressed by the real and imaginary parts of refractive indexof the magnetized plasma, with clear physics meaning. Furthermore, the dependence of Faradayangle on collision frequency is calculated and discussed.
