Acircularly polarized source at incident angle .7854 impinges on dielectric slab of relative permittivity 4. Brewster angle of 1.107 is plotted. Source is rotated to Brewster angle to show reflected radiation is linearly polarized. Reflection and transmission parameters for parallel polarization are plotted as source is rotated. Reflection and transmission parameters for perpendicular polarization are plotted as source is rotated. Field intensities at interface are computed.
