Compute the value of the unknown load impedance, Z L . 7) A TM mode is excited in a parallel-plate waveguide filled with a dielectric of ε = 4 ε and μ = μ and having the plates in the x = 0 and x = 5 cm planes by setting up at its input z = 0 the magnetic field distribution 9 ˆ cos40 sin8 10 H H x t y π = × . Find the expressions for the electric and magnetic fields of the propagating wave. 8) For the parallel-plate waveguide discontinuity shown below, find the power reflection coefficient for f = 7500 MHz for the TEM mode and the TE 10 mode....
