Xz. Wu et F. Mariotte, A NEW RADIAL TRANSMISSION-LINE NETWORK APPROACH FOR SYMMETRICAL MODESIN CIRCULAR CHIROWAVEGUIDES, International journal of infrared and millimeter waves, 18(11), 1997, pp. 2259-2275
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.
