A uniform plane wave with H =ỹH, propagates in a lossless simple medium (€, = 9,4, =1,0 =0) in the + z-direction. Assume that H is sinusoidal with a frequency 500 MHz and has a maximum value of +10-3 V/m at t = 1 ns and z = 0.25 m. (20%) Mor 44x10! Eo 109 () Es = (a) Write the instantaneous expression for A and Ē for any t and z. (b) Determine the location where H, is a positive maximum when t = 10 ns. (c) Plot Ä and Ē as a function of z in the same coordinates for t = 0 ns.
