Query: A perturbative approach to calculating the Casimir force in fluctuating
  scalar and vector fields   Based on a perturbative approach, a series expansion in susceptibility
function of the medium is obtained for the Casimir force between arbitrary
shaped objects immersed in a scalar or vector fluctuating field in arbitrary
dimensions. Finite-temperature corrections are derived and the results are
compared in first order with weak coupling regime in scattering method. The
generalization to a massive vector field is also investigated.
