Abstract
The theoretical properties of a composite chiral-ferrite medium are de veloped. The composite is constructed from a general chiral medium and a nonreciprocal ferrite medium. Application of the reaction theorem a llows 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 dir ect space dyadics are then determined. Characteristic dispersion equat ions 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 equa tion through coordinate rotation allows major and minor axis determina tion.
