ANALYSIS OF COAXIAL WAVE-GUIDE PARTIALLY FILLED WITH CHIRAL MEDIA

In this paper, the canonical problem of coaxial waveguide partially fi lled with chiral media is analyzed by a new equivalent transmission li ne network method. Both radial transmission lines in the cross section and multi-mode transmission lines in the longitudinal direction are i ntroduced. The symmetrical properties of the structure are also discus sed. Therefore, this method brings a clear physical picture into the w ave propagation phenomena. Based on the analysis, the notable features and the role of the chirality parameter of the medium on the reflecte d and transmitted guided waves are discussed.
