Modelling of transmission through a chiral slab using fractional curl operator

Transmission of electromagnetic plane wave through a slab of reciprocal chiral medium has been modelled using fractional curl operator. It is noted that when order of the fractional curl operator becomes zero, the equivalent situation may correspond to absence of the chiral slab. Variation of the order of fractional curl operator may explore situations which may be regarded as intermediate step of a situation dealing with no chiral slab and a situation dealing with a chiral slab. It is noted that real order of the fractional curl operator may model the optical rotation while complex order of the fractional curl operator may model optical rotation as well as circular dichroism.
