EE325-Fall 2009 Problem Set 11 Problem 1 Problem 12.23 in the textbook. Problem 2 Problem 13.1 in the textbook. Problem 3 Problem 13.3 in the textbook. Problem 4 The plane 0 z = defines the boundary between air ( 0 z < ) and a dielectric material ( 0 z > ) with 3, 1 r r ε μ = = . Let the electric field phasor of the incident plane wave be 15 1 ˆ 10 V/m j z s x e + = E a . Find a) the frequency f b) the reflected wave 1 s E in air c) the transmitted wave 2 s + E in the material d) the time averaged Poynting vector for the transmitted wave 2 + < > S e) the percentage of the power reflected from the boundary f) the percentage of the power transmitted into the dielectric
