The dispersion equation of an asymmetric three-layer slab waveguide,in which all layers are chiral materials is presented.Then,the dispersion equation of a symmetric slab waveguide,in which the claddings are chiral materials and the core layer is negative index material,is derived.Normalized cut-off frequencies,field profile,and energies flow of right-handed and left-handed circularly polarized modes are derived and plotted.We consider both odd and even guided modes.Numerical results of guided low-order modes are provided.Some novel feattures,such as abnormal dispersion curves,are found.
