Phys. Rev. A 72, 032112 (2005) [16 pages]Ground-state van der Waals forces in planar multilayer magnetodielectricsReceived 28 February 2005; published 30 September 2005 Within the frame of lowest-order perturbation theory, the van der Waals potential of a ground-state atom placed within an arbitrary dispersing and absorbing magnetodielectric multilayer system is given. Examples of an atom situated in front of a magnetodielectric plate or between two such plates are studied in detail. Special emphasis is placed on the competing attractive and repulsive force components associated with the electric and magnetic matter properties, respectively, and conditions for the formation of repulsive potential walls are given. Both numerical and analytical results are presented. © 2005 The American Physical Society URL:
