(b) verify that the average power transmite P.8-38 A uniform plane wave of angular frequency w in medium 1 having a refractive index n, is incident on a plane interface at z = 0 with medium 2 having a refractive index nz (<n) at the critical angle. Let E;o and Exo denote the amplitudes of the incident and refracted electric field intensities, respectively. a) Find the ratio Exo/E;0 for perpendicular polarization. b) Find the ratio E.0/E;0 for parallel polarization. c) Write the instantaneous expressions of Ef(x, z; t) and E,(x, z, t) for perpendicular polarization in terms of the parameters w, ny, n2, 0;, and E10- rith perpendicular polariza-
