Bending of a light ray within a dispersive medium in a uniform gravitational field

TL;DR

This paper explores how light bends in a dispersive medium under a uniform gravitational field using general relativistic theory, extending previous work on frequency-dependent dispersion effects.

Contribution

It applies Synge's general relativistic framework to analyze light bending in dispersive media within a gravitational field, providing a theoretical extension of prior studies.

Findings

Derived new equations for light propagation in dispersive media under gravity.

Extended previous models to include general relativistic effects.

Provided insights into frequency-dependent light deflection in gravitational fields.

Abstract

Recently, Dressel et al determined the vertical deflection of a light ray in a medium, with a strong frequency-dependent dispersion, at rest in a uniform gravitational field. We take up this question within the general relativistic theory of the propagation of light in a dispersive medium, due to Synge.
