Casimir Energy For Perfect Electric Conductors Revisited

摘要

The Casimir energy has been calculated using the path integral method [2], [3] for a geometry of cylindrical perfect electric conductors. A similar derivation is proposed by making use of a decomposition rule for the calculation of functional determinants in terms of the Fourier components of Greens functions. This method yields a set of different impedance matrices that are validated analytically for the parallel plate geometry.
