is incident upon the planar surface of a dielectric material, with &, = 4, occupying the half space z ≤ 0.
Determine
1. The polarization of the incident wave
2. The angle of incidence
3. The time-domain expressions for the reflected electric and magnetic fields
4. The time-domain expression for the transmitted electric and magnetic fields
5. The average power density carried by the wave in the dielectric medium.
