Abstract
In this paper, the dispersion characteristics of symmetrical modes in circular chirowaveguides are analyzed by a new equivalent transmission line network method. Radial transmission lines in the transverse cros s section are introduced. In the transmission line network, the right- circularly polarized (RCP) wave and the left-circularly polarized (LCP ) wave can propagate independently in the uniform regions and couple o nly at the interface. Therefore, this method brings a clear physical p icture into the wave propagation phenomena. Based on the analysis, two interesting effects due to mode coupling and leakage are carefully st udied.
