Waveguide Junctions

Abstract

Abstract The properties of n ‐port waveguide junctions are described in fundamental terms, with methods for finding impedance and admittance representations from the scattering matrix, leading to equivalent‐circuit representations. Some of the general properties of n ports are treated, with most examples dealing with three‐ and four‐port junctions. Three‐port networks include E ‐ and H ‐plane T junctions and E ‐plane bifurcations, and the discussion of four ports includes magic‐Ts and ring hybrids. Emphasis is placed on fundamental properties, the understanding of which is important for future research.
