Impedance and propagation in ridge waveguides using the transverse resonance method

Important quantities in the description of any waveguide are the definition of its propagation constant and the voltage-current, power-voltage and power-current definitions of its characteristic impedance. One purpose of this chapter is to summarise some closed form descriptions of propagation, power flow and impedance in the ridge waveguide based on the transverse resonance method (TRM). Since the different notations introduced in its characterisation are on occasion difficult to follow readily, another purpose of this chapter is to reproduce the existing literature in a single nomenclature. Still another is to summarise graphically its voltage-current, power voltage and power-current definitions of impedance in a unified way.
