Impact of Chirality on the Properties of Two-Dimensional Images Propagating Through a Chiral Dispersive Thick Lens

2025-05-03 · Salaheddeen Bugoffa, Hussin Ragb

Dual image formation for a two-dimensional object via bimodal propagation through chiral-dispersive thick lens is derived. In this article, first-order frequency-dependent material dispersion of the dielectric permittivity and the lens material being chiral are considered. In addition, the thick lens is configured in a uniform background. A salient feature of a chiral thick lens is the inherent bimodal propagation via circular polarizations. Under chirality, two sets of ABCD frequency dependent matrices are derived for right- and left-circularly polarized modes based on standard paraxial and meridional conditions. For imaging purposes, a simple2D colored transparency is placed as an object before the thick lens. The image transmission across the lens examined via the ABCD matrix parameters and defocusing effects due to dispersion under different chirality bands.
