Abstract

Heuristic solutions are provided to evaluate the diffraction by uniaxial chiral screens that are isolated or arranged in planar junctions. The optical axial direction of the chiral medium is perpendicular to the screen surfaces. Plane waves at skew incidence with respect to the discontinuity of the structure are considered and the proposed solutions are built in accordance with the uniform geometrical theory of diffraction by using the reflection and transmission matrices at the shadow boundaries for the reflected and incident/transmitted electric fields. Note that the importance of this research work relies on the absence of exact and approximate analytical solutions for the considered problems. Renowned commercial software is customized and expended to validate the results.
