The paraxial propagation of a beam incident along an optic axis of a biaxial crystal slab is
studied in detail. Analytical descriptions are given for the Poggendorff bright and dark rings …

The review is devoted to theoretical and experimental problems in the study of liquid crystals
by light scattering methods. Nematic, cholesteric, and smectic liquid crystals in the isotropic …

The Fourier optics technique is founded on the transfer function derived from the scalar
wave equation and thus has traditionally been applied to monochromatic scalar fields …

The dyadic Green function for an anisotropic, inhomogenous medium is reformulated as a
double differential form by embedding material properties in the Hodge star operator. This …

In this paper we discuss the theory of the internal conical refraction of coherent light beams.
A mathematical description of the distribution of intensity in the ring of Gaussian and Bessel …

This paper is devoted to the derivation of the equations that govern the propagation of
pulses in noncentrosymmetric crystals. The method is based upon high-frequency …

ABSTRACT A review of basic papers related to development and implementation of rather
efficient mathematical methods aimed at formation of Green's functions for various types of …

We set up the electromagnetic system and its plane-wave solutions with the associated
slowness and wave surfaces. We treat the Cauchy initial-value problem for the electric …

This paper treats the phenomenon of internal conical refraction, in which a narrow beam
propagating along an optical axis of a biaxial anisotropic medium spreads into a hollow …
