The Casimir Polder force on a small polarizable particle (a ``point'' particle) situated in a wedge-shaped cavity with perfectly conducting walls is calculated, at zero temperature. Various special cases are examined. In particular, agreement with the conventional Casimir Polder formula is obtained

β¦ Synopsis
The Casimir effect is considered for a wedge with opening angle Ξ±, with perfectly conducting walls, when the interior region is filled with an isotropic and nondispersive medium with permittivity and permeability Β΅. 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.

The vacuum energy density of electromagnetic field inside a perfectly conducting wedge is calculated by making use of the local zeta function technique. This regularization completely eliminates divergent expressions in the course of calculations and gives rise to a finite expression for the energy
Fields scattered by a lossy dielectric wedge for a plane-wa¨e incidence are calculated. Reflected and refracted fields are obtained by inhomogeneous plane-wa¨e tracing in a lossy medium, while the edgediffracted fields of the physical-optics approximation are accurately corrected by adding the multi
We analyze the high temperature (or classical) limit of the Casimir effect. A useful quantity which arises naturally in our discussion is the "relative Casimir energy," which we define for a configuration of disjoint conducting boundaries of arbitrary shapes, as the difference of Casimir energies be
