Unformatted text preview: ECE 329 Homework 8 Due: Tuesday, March 17, 2009, 5PM 1. In material media, phasor form of Faradays and Amperes laws, E =- j B =- j H and H = J + j D = E + j E = ( + j ) E , have + j in place of j o , and in place of o as compared to the same equations in vacuum. As a consequence, divergence-free plane wave solutions with phasors E = xE o e z and H = y E o e z have, instead of the wave parameters = j o o = ( j o )( j o ) and = o o = j o j o as in vacuum, the modified wave parameters = ( j )( + j ) and = j + j . a) Calculate the numerical values of the propagation constant + j and intrinsic impedance , if wave frequency f = 2 = 10 3 Hz and the medium parameters are = o , = 81 o , and = 4 S/m, corresponding to sea water....
