Visualization of traveling-wave snapshots in space. Write a MATLAB code that calculates and plots the electric field intensity of a time-harmonic uniform plane wave propagating in air, given by E_x(z, t) = 2cos(ωt − βz) V/m [see Eqs.(7.1)], at time instants t = 0, t = T/2, and t = T (T is the time period of the wave) in a region of space defined by 0 ≤ z ≤ 12 m, if the frequency of the wave is f = 100 MHz. (ME7 2.m on IR)

HINT:

Use function propParamLossless (from the previous MATLAB exercise), to compute the necessary propagation parameters for the wave. The resulting E-field snapshots for the wave are shown in Fig.7.2, where the three subplots, for the three time instants, are obtained by MATLAB function subplot (see MATLAB Exercise 3.3).
