ELEG 320 ELECTROMAGNETIC FIELD THEORY I HOMEWORK #6 – DUE NOVEMBER 23, 2010 1) Problem 2.26 6th Edition (2.59 5th Edition) 2) Problem 2.40 6th Edition (2.28 5th Edition) 3) Problem 2.23 6th Edition (2.15 5th Edition) 4) Problem 2.31 6th Edition. Ignore part d. (2.21 5th Edition) 5) Problem 2.33 6th Edition (2.23 5th Edition) 6) Let us assume that measurements performed on a slotted line of characteristic impedance Z 0 = 50 provided the following data. First, with the short circuit as the termination, voltage minima were found to be 20 cm apart. Next, with one of the minima marked as the reference point and the short circuit replaced by the unknown load, the SWR was found to be 3.0 and a voltage minimum was found to be at 5.80

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....
