and Mr 1. A uniform plane wave propagates in gold with properties o = 4.1 x 107 S/m, er = 1, = 1. The wave is propagating in the +z direction. At z = 0 the electric field in V/m is given by Ē(z,t) = ĉ5cos(5 x 104rt) (1) Show your work as you determine the

general expression for the instantaneous electric field, E(2,t). general expression for the instantaneous magnetic field, H(2,t). time average power density, Sav (2). distance over which the time-average power density is reduced by 90%
