1. Why is the dimension b of a rectangular waveguide generally chosen to be less than or equal to one-half the dimension a?

2. What is a cavity resonator?

3. How do the dimensions of a rectangular cavity resonator determine the frequencies of oscillation of the resonator?

4. Discuss the condition required to be satisfied by the incident, reflected, and transmitted waves at the interface between two dielectric media.

5. What is Snell's law?

6. What is meant by the plane of incidence? Distinguish between the two different linear polarizations pertinent to the derivation of the reflection and transmission coefficients for oblique incidence on a dielectric interface.
