Wave propagation in unidirectionally inhomogeneous chiral media is examined, i.e. the constitutive properties of the chiral media vary along the z axis; it is also assumed that the electromagnetic field is a function of the z coordinate alone. It is shown that the electromagnetic field, in the present arrangement, can be decomposed into two mutually-independent circularly-polarized states. Coupled first-order differential equations are derived to describe the fields, and various solution procedures discussed. Extension is made to the case when the medium inhomogeneity is periodic, for which case a perturbational solution is explicitly given.
