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...

2._A homogeneous dielectric medium, with dielectric constant , occupies not only the region < 0 as discussed in this chapter, but also the region z a > 0. A unit point charge is stationed in the vacuum between the dielectrics, a>z0. Use any method to find the function g in the three regions. What happens as a oo, and as a0?
