(a) A linearly polarized electromagnetic waye with polarization normal to the plane of incidence is incident obliquely on a dielectric nedium of relative permittivity e,. Find the reflected (E,) and transmitted (E) wave amplitude as a function of the incidence angle 6. Plot schematically the reflection coefficient as a function of the incidence angle 0 for the cases E, <1 and , > 1.
