Casimir Effect for a Dielectric Wedge

Abstract

The Casimir effect is considered for a wedge with opening angle $\alpha$, with perfectly conducting walls, when the interior region is filled with an isotropic and nondispersive medium with permittivity $\epsilon$ and permeability $\mu$. The electromagnetic energy-momentum tensor in the bulk is calculated, together with the surface stress on the walls. A discussion is given on the possibilities for measuring the influence of the medium, via the Casimir-Polder force.
