Perturbation approach to the Casimir force between two bodies made of
different real metals
B. Geyer, G. L. Klimchitskaya, V. M. Mostepanenko
abstract: The Casimir force acting between two test bodies made of different metals is
considered. The finiteness of the conductivity of the metals is taken into
account perturbatively up to the fourth order of the relative penetration
depths of electromagnetic zero-point oscillations into the metals. The
influence of nonzero temperature is computed explicitly for separate orders of
perturbation and found to be important in the zeroth and first orders only. The
configurations of two parallel plates and a sphere (spherical lens) above a
plate are considered made of $Au$ and $Cr$. The obtained results can be used to
take into account also the surface roughness. Thus, the total amount of the
Casimir force between different metals with all correction factors is
determined. This may be useful in various applications.
