b) The TEM wave of Q3.a) is incident normally onto a flat, thick slab of polymer, assumed to be lossless and with a relative permittivity of Er = 2.25. (i) Calculate the rms reflected and transmitted power fluxes at the surface of the polymer and write down row vector expressions for the electric fields of the reflected and transmitted waves. (ii) Describe briefly what happens in the air space outside the polymer and calculate the maximum and minimum values of E-field amplitude, noting their precise positions relative to the polymer surface. 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 E = (Ex, Ey, E₂) = (0, E₁ expj (wt - Box),0)
