Q3. a) A TEM plane wave propagates in air with a wavelength of 20 = 1.25m and an rms power flux of 1.57μW/m². Its electric field in Cartesian coordinates is (i) E = (Ex, Ey, Ez) = (0, E₁ expj (wt - Box), 0) Calculate the values of its amplitude Eo, period T, phase constant ẞo and state the portion of the EM spectrum it occupies. (ii) Use one of Maxwell's equations to derive a similar expression for the wave's magnetic field H and draw a simple sketch showing the relative orientations of E, H and power flux, at any instant of your choice.
