Waves in weakly anisotropic 3D inhomogeneous media: quasi-isotropic approximation of geometrical optics

Kravtsov, Yu A, Naida, O N, Fuki, A A·1996·Physics-Uspekhi

Abstract

The quasi-isotropic approximation (QIA) of geometrical optics is outlined. The main idea of the method is that electromagnetic waves in weakly anisotropic media preserve their transverse structure as they do in isotropic media. Advantages of the QIA are illustrated by considering electromagnetic wave propagation in plasma, a number of optical problems (liquid crystals, hiral media, single mode optical fibres), acoustical problems of weakly anisotropic elastic media, and quantum mechanical polarisation effects of the Stern–Gerlach type. New modifications of the QIA are presented, namely the method of split rays and the synthetic approach, the latter being applicable even for strongly anisotropic media.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
