QUESTION 6 A wave with E = ( 10) e-0.2z e-j0.2z (V/m) is traveling in a good conducting medium with o = 4 S/m in the downward 2 direction with z = 0 representing the surface (or boundary). The average power density of the wave in the medium is given by Šav (2) = ½ Re [Ẽ × Ã·] = 2 ¹¹²e-2a² cos (0,₁). Find the depth in the medium at which the average power density is reduced by 30 dB (or 10³).
