Analysis of the Faraday rotation in a magnetized plasma

To know about Faraday rotation effect and make use of it for polarization interference, the mechanism of arising of Faraday rotation effect is analyzed when linearly polarized electromagnetic waves transmit through magnetized plasma. Then, the dispersion relations of the LCP (Left Circularly Polarized) wave and the RCF (Right Circularly Polarized) wave are given out. Sequentially, the formula for calculating Faraday rotation angle is derived out too. To validate the existence of the Faraday rotation effect, the relations between Ex component and Ey component are presented out and the Faraday rotation angle varying principles with different plasma parameters versus EM-waves frequency are obtained by using numerical method. As a result, Faraday rotation effect can be used to make interference in electronic countermeasure field.
