The classical limit of quantum optics: not what it seems at first sight
New Journal of Physics, 2013 What light is and how to describe it has always been a central subject in physics. As our understanding has increased, so have our theories changed: geometrical optics, wave optics and quantum optics are increasingly sophisticated descriptions, each ...

Physical-geometric optics method for large size faceted particles.
Optics Express, 2017 A new physical-geometric optics method is developed to compute the single-scattering properties of faceted particles. It incorporates a general absorption vector to accurately account for inhomogeneous wave effects, and subsequently yields the relevant ...

Scattering of ECRF waves by edge density blobs and fluctuations in tokamak plasmas
EPJ Web of Conferences, 2012 There are two basic approaches to studying the effects of density blobs and edge fluctuations on the coupling of electron cyclotron (EC) radio frequency waves to the core of tokamak plasmas.

Supercritical geometric optics for nonlinear Schrodinger equations [PDF]
, 2007 We consider the small time semi-classical limit for nonlinear Schrodinger equations with defocusing, smooth, nonlinearity. For a super-cubic nonlinearity, the limiting system is not directly hyperbolic, due to the presence of vacuum.

Ray and wave dynamics in a static FRW spacetime with conical singularity
Physics Letters BIn this paper, we investigate a (1+3)-dimensional static Friedmann-Robertson-Walker (FRW) space-time, pierced by a cosmic string. Our analysis begins with a detail study of the geodesic motion of photon rays in this curved background, focusing on the ...

Angular momentum redirection phase of vector beams in a non-planar geometry
Nanophotonics, 2021 An electric field propagating along a non-planar path can acquire geometric phases. Previously, geometric phases have been linked to spin redirection and independently to spatial mode transformation, resulting in the rotation of polarisation and ...

A differential geometry approach to asymmetric transmission of light
, 2017 In the last ten years, the technology of differential geometry, ubiquitous in gravitational physics, has found its place in the field of optics. It has been successfully used in the design of optical metamaterials, through a technique now known as ...
