TL;DR: In this article, the interplay between ray fields and mode fields, on the excitation mechanism of each, and on their properties when the field incidence angle is strongly oblique, was studied.

TL;DR: The fast-developing domain of microwave optics is surveyed, with main emphasis on those aspects of interest to optical scientists.
Abstract: The fast-developing domain of microwave optics is surveyed, with main emphasis on those aspects of interest to optical scientists. Special attention is devoted to the newer trends in that field of research. The following aspects are covered: diffraction theory of microwave optics, microwave optical instruments, beam waveguides, and components for millimeter waves.

TL;DR: It is shown that the vector field decomposition method, namely, the Helmholtz Hodge decomposition, can also be applied to analyze scalar optical fields that are ubiquitously present in interference and diffraction optics.
Abstract: It is shown that the vector field decomposition method, namely, the Helmholtz Hodge decomposition, can also be applied to analyze scalar optical fields that are ubiquitously present in interference and diffraction optics. A phase gradient field that depicts the propagation and Poynting vector directions can hence be separated into solenoidal and irrotational components.

TL;DR: The geometrical and wave optics for light emerging from a slab of transparent biaxial crystal with optical activity (chirality) for an incident beam directed along the optic axis were explored in this article.
Abstract: The geometrical and wave optics are explored for light emerging from a slab of transparent biaxial crystal with optical activity (chirality), for an incident beam directed along the optic axis. The geometrical optics, here derived from Hamilton's principle, is dominated by a circularly symmetric cusped caustic surface ('spun cusp') threaded by an axial focal line. In wave optics, formulated exactly in the paraxial approximation in terms of integrals previously obtained by Belsky and Stepanov and here derived using a unitary evolution operator, the field is determined by two dimensionless parameters. The geometrical features are decorated by interference, here explored in the focal image plane (where the Poggendorff rings of the non-chiral case are in sharpest focus) and along the axis. Asymptotic approximations are derived in terms of the geometrical optics rays (including interference and evanescent waves), near the spun cusp, and uniformly across the caustic surface far from the cusp.
