a, plane wave in aiv with

is incident upon the planar surface of a dielectric material, with εr = 2.25, occupying the half-space z ≥ 0. Determine

(a) The incidence angle θi

(b) The frequency of the wave.

(c) The field of the reflected wave.

(d) The field of the wave transmitted into the dielectric medium.

(e) The average power density carried by the wave into the dielectric medium.
