Question

Consider the grounded dielectric sheet in figure below. The thickness d 2 mm and its relative permittivity is 3 (1) Numerically calculate the propagation constant of the dominant TM mode using either the Newton-Raphson method or the fzero function of Matlab for wavelength range from d to 100d. (2) Calculate the Ez field at 40 GHz for x ranging from 0 to 5d. Plot the normalized propagation constant and Ez, sample plots are given below Dielectric Ground plane d-1mm, f 20 GHz 0.8 1.8 0.6 0.4 0.2 1.2 0 0.2 0.4 0.6 0.8 0 3 5 x (m) x10
