ABSTRACT
The theory of microwave cavities and their application to radar technology was largely developed during World War II. This chapter considers some of the elementary aspects of electromagnetic waveguides, which is closely tied to the electrostatic mode theory. It introduces the theory of waveguides, especially relevant for microwave radiation. The chapter discusses transverse magnetic modes and transverse electric modes, cylindrical waveguides with arbitrarily shaped surfaces, boundary conditions, and cross section of waveguides consisting of inner and outer conductors.
