electromagnetic wave is incident normally (along the y-direction) from A 159 MH Zair onto a lossless dielectric medium (ɛr = 2.25, 0

5 V/m along the x-direction. Write the wave expressions of the reflected E.(r.t) off thefrist surface, and the final transmitted Hi(r,t). Ignore the phase shift due to the finite thịckness of the dielectric. If the incoming wave is 2 mW of RF power, what are the reflected power (first reflection only) and the final transmitted power in dBm? Consider only the initial reflections at the first and second boundary. Ignore all multiple reflections thereafter,
