Casimir force between designed materials: what is possible and what not
arXiv:quant-ph/0407153 · doi:10.1209/epl/i2005-10344-3
Abstract
We establish strict upper limits for the Casimir interaction between multilayered structures of arbitrary dielectric or diamagnetic materials. We discuss the appearance of different power laws due to frequency-dependent material constants. Simple analytical expressions are in good agreement with numerical calculations based on Lifshitz theory. We discuss the improvements required for current (meta) materials to achieve a repulsive Casimir force.
