title: Pairwise summation approximation of Casimir energy from first principles.
abstract: We obtain the pairwise summation approximation (PSA) of the Casimir energy from first principles in the soft dielectric and soft diamagnetic limit, this analysis let us find that the PSA is an asymptotic approximation of the Casimir energy valid for large distances between the objects. We also obtain the PSA for the electromagnetic coupling part of the Casimir energy, so we are able to complete the PSA limit for the first time for the complete electromagnetic field.
