Abstract: We present a method of computing Casimir forces for arbitrary geometries,with any desired accuracy, that can directly exploit the efficiency of standardnumerical-electromagnetism techniques. Using the simplest possiblefinite-difference implementation of this approach, we obtain both agreementwith past results for cylinder-plate geometries, and also present results fornew geometries. In particular, we examine a piston-like problem involving twodielectric and metallic squares sliding between two metallic walls, in two andthree dimensions, respectively, and demonstrate non-additive and non-monotonicchanges in the force due to these lateral walls.
