2 (50 points) Consider the geometry of Fig. 2 referring to a time-harmonic uniform plane wave with angular frequency that is obliquely incident on the plane boundary that separates two half-spaces with properties 1, 1 and 2, 2 respectively. The incident wave is linearly polarized and its electric field is contained in the plane of incidence so that this is a case of parallel polarization. Derive expressions for the incident, reflected, and transmitted electromagnetic field
