Two lossy homogeneous dielectric media with dielectric constans r l = 2, r 2 = 3 and conductivities a 1 = 15 (mS), 2 = 10 (ms) are in contact at the z = 0 plane. In the z 0 region (medium 1) a uniform electric field E 1 = a x 20 a z 50 (V/m) exists. Find (a) E 2 in medium 2, (b) J 1 and J 2 , (c) the angles that J y and J 2 make with the z = 0 plane, and (d) the surface charge density at the interface.
