An article and method for controlling the sign (repulsion or attraction) and magnitude of dispersion forces, such as the Casimir force. In accordance with one embodiment of the present teachings, dispersion forces are controlled by selectively reflecting only those spectral components (i.e., frequencies) at which the random oscillations of the electromagnetic field contribute to the force behavior desired, while substantially suppressing all other spectral components. In one embodiment, the selected spectral components are omni-directionally reflected using photonic band gap materials.
