摘要：

The theoretical properties of a composite chiral-ferrite medium are developed. The composite is constructed from a general chiral medium and a nonreciprocal ferrite medium. Application of the reaction theorem allows proof of nonreciprocity based on the constitutive relationships. Vector Helmholtz E-and H-field equations are derived, and from these equations reciprocal space Green's function dyadics are found. The direct space dyadics are then determined. Characteristic dispersion equations are found from the sourceless vector phasor Helmholtz equations. E-field polarization is obtained by projecting the E field vector onto the polarization plane selected. Diagonalization of the elliptic equation through coordinate rotation allows major and minor axis determination.
