Theory shows that a slab of a dielectric structurally chiral material (DSCM) exhibits both linear and circular dichroisms because of its anisotropy and structural chirality, for normal as well as oblique incidence. This conclusion was confirmed by fabricating a chiral sculptured thin film and measuring the spectra of its reflectances and transmittances, both linear and circular. Signatures of the circular Bragg phenomenon are evident in the spectra of all reflectances, transmittances…

Spin-orbit interactions and chiroptical effects engaging orbital angular momentum of twisted light in chiral and achiral media
There is recurrent interest in the orbital angular momentum (OAM) conveyed by optical vortices, which are structured beams with a helically twisted wave front. Particular significance is attached to
Symmetries, Conserved Properties, Tensor Representations, and Irreducible Forms in Molecular Quantum Electrodynamics
In the wide realm of applications of quantum electrodynamics, a non-covariant formulation of theory is particularly well suited to describing the interactions of light with molecular matter, and a variety of symmetry principles are drawn out with reference to applications.


Experimental investigation of circular Bragg phenomenon for oblique incidence.
A variable-angle spectroscopic system was devised and used to measure all eight of the circular remittances of the chiral STF as functions of the angle of incidence and the free-space wavelength, and the chosen representation was found adequate to represent the blue shift of the centerwavelength with an increasing angles of incidence.
The circular Bragg phenomenon
Exhibited by structurally chiral materials—such as Reusch piles, cholesteric liquid crystals (CLCs), and chiral sculptured thin films (STFs)—due to their helical nonhomogeneity along a fixed axis,

Experimentation with obliquely incident light established that all four circular reflectances of a chiral sculptured thin film backed by a metallic mirror contain strong evidence of the circular
Vacuum deposition of chiral sculptured thin films with high optical activity.
The technique of bideposition is presented to realize thin-film helicoidal bianisotropic mediums (TFHBM's) that exhibit high optical activity and shows that the optical rotation produced by these chiral sculptured thin films is roughly proportional to the square of the local linear birefringence.
Reflection and transmission of obliquely incident light by chiral sculptured thin films fabricated using asymmetric serial-bideposition technique
Abstract. Chiral sculptured thin films (STFs) were grown using the asymmetric serial-bideposition (ASBD) technique, whereby (i) two subdeposits of unequal heights are separated by a substrate
On optical rotation and ellipticity transformation by axially excited slabs of dielectric thin‐film helicoidal bianisotropic mediums (TFHBMs)
The tilt angles and the ellipticities of transmitted and reflected plane waves are shown to be different from those of plane waves normally incident on slabs of dissipative dielectric thin-film
Spectral signatures of axially excited slabs of dielectric thin-film helicoidal bianisotropic mediums
Dielectric thin-film helicoidal bianisotropic mediums (TFHBMs) are rotationally nonhomogeneous nano-engineered materials of recent vintage. Here, optical signatures of axially excited TFHBM slabs are
