8.2 A plane wave traveling in medium 1 with ef1 = 2.25 is normally incident upon medium 2 with e,2 made of nonmagnetic, nonconducting materials. If the electric field of the incident wave is given by :4. Both media are E' = ŷ8 cos(67 × 10°t – 307x) (V/m). (a) Obtain time-domain expressions for the electric and magnetic fields in each of the two media. (b) Determine the average power densities of the incident, reflected, and transmitted waves.
