A plane wave traveling in a medium with r1 = 9 is normally incident upon a second medium with r2 = 4. Both media are made of nonmagnetic, non-conducting materials. If the magnetic field of the incident plane wave is given by
(a) obtain time domain expressions for the electric and magnetic fields in each of the two media, and



(b) Determine the average power densities of the incident, reflected and transmitted waves.
