Gravitational Lensing as a Mechanism For Effective Cloaking
arXiv:1108.3793 · doi:10.1103/PhysRevD.84.104034
Abstract
In light of the surge in popularity of electromagnetic cloaking devices, we consider whether it is possible to use gravitational lensing to cloak a volume of spacetime. A metric for such a spacetime geometry is presented, and its geometric and physical implications are explained.
