Question: Consider a uniform plane wave having E = Ex(z, t), and H = H, (z,t), and propagating in the +z direction in a lossless

Consider a uniform plane wave having E = Ex(z, t), and H = H, (z,t), and propagating in the +z direction in a lossless dielectric medium. The time variation of Ex in a constant z-plane and the distance variation of Hy for a fixed time are observed to be sinusoids and shown in the following figures. (Warning: Amplitudes shown are peak to peak) Ex(t) N min 10 ns 9 V/m 0.2 A/m a) What is the intrinsic impedance of the medium? b) What is the propagation constant (wave number)? c) What is the phase velocity? H,(z) 0.5 m d) Find the relative permittivity and permeability of the medium? e) Write time domain expressions for electric field intensity and magnetic field intensity vectors.
