Reflection and transmission of normally-incident plane waves by a chiral slab with linear properties variations

Reflection and transmission of normally-incident plane waves by a chiral slab with linear property variations Reflection by and transmission through a chiral slab are explored for normally incident plane waves, it being assumed that the constitutive parameters of the slab vary along the direction of incidence. It is shown that the Faraday and the Ampere-Maxwell equations decompose into two autonomous matrix differential equations. The effect of the chiral slab is accounted for by the matrices S ± that are evaluated for a linearly inhomogeneous chiral slab using two methods
