The electric field intensity of a smooth plane wave spreads into the ocean (er = 76, ur = 1,0 = 4 S/m) in the direction (-2). Electric field strength on the surface of the ocean (z = 0) H (0, t) = -ây2cos (81106t +13) (A / m) is given. a) Determine the skin thickness and the impedance of the ocean water. b) Find the expressions E (z, t) and H (z, t) in the ocean. c) Find the power loss per unit area in the ocean as a function of z.
