Generalized plasma-like permittivity and thermal Casimir force between real metals
arXiv:0710.0254 · doi:10.1088/1751-8113/40/44/025
Abstract
The physical reasons why the Drude dielectric function is not compatible with the Lifshitz formula, as opposed to the generalized plasma-like permittivity, are presented. Essentially, the problem is connected with the finite size of metal plates. It is shown that the Lifshitz theory combined with the generalized plasma-like permittivity is thermodynamically consistent.
