The polarization of light is quite frequently observed in nature and with other properties like amplitude, frequency and phase of an Electromagnetic (EM) wave, it constitutes one of the most fundamental quantities, which completely describes it. In Physics and Optics, the polarization of light is studied through ”Faraday Rotation Effect” using optical materials like glass, crystals, chemicals etc. Its analogue in radio waves is transmission of polarized wave in ferrites materials. The idea is to study the potential of fast polarization modulation for data communication, which is not much explored yet.
