Coupling transmission waveguides
WebSection 12.8 reviews the theory of the cylindrical waveguide. Waveguides are extended hollow metal structures of uniform cross section. Traveling waves are contained and … WebIn this work, we present an accurate coupled transmission line model for different metal-insulator-metal waveguide based arrangements. The coupling regions are modeled by appropriate characteristic impedances and propagation constants for both even and odd modes, which are calculated from the metal-insulator-metal waveguide parameters.
