Electromagnetic Wave Theory
Kong Problem 3-35
In a parallel-plate waveguide, the region z < 0 is free space
and the region z > 0 is filled with a dielectric medium having
permittivity 
. How would you write the modes for both regions? For a TM mode
incident upon the dielectric from the z < 0 region, show that
there is no reflected wave when 
. Compare this result with the case of a wave incident upon a
half-space medium at the Brewster angle.
