A plane wave traveling in medium 1 with ϵr1 = 2.25 is normally incident upon medium 2 with ϵr2 = 4. Both media are made of nonmagnetic, non-conducting materials. If the electric field of the incident wave is given by

Ei = ŷ4 cos(6π × 109t − 30π x) (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.
