Exercise 44

Assume that a TE wave of a frequency f is launched along the z -direction in the parallel-plate waveguide in Fig.9-3. The dielectric medium between the plates has constitutive parameters and . (a) Find the phasor expression for
. (b) Find the cutoff frequency for the TE 1 mode. (c) Write the instantaneous expression for all the field components of the TE 1 mode.
