1. Discuss the nomenclature associated with the modes of propagation in a rectangular waveguide.
2. Explain the relationship between the cutoff wavelength and the dimensions of a rectangular waveguide based on the phenomenon at cutoff.
3. Why can there be no transverse magnetic modes having no variations for the fields along one of the dimensions of a rectangular waveguide?
4. What is meant by the dominant mode? Why are waveguides designed so that they propagate only the dominant mode?
