Long range Casimir force induced by transverse electromagnetic modes

We consider the interaction of two perfectly conducting plates of arbitrary shape that are inside a nonsimply connected cylinder with transverse section of the same shape. We show that the existence of transverse electromagnetic (TEM) modes produces a Casimir force that decays only as 1/a2, where a...
