Exterior cloaking with active sources in two dimensional acoustics. Guevara Vasquez, F., Milton, G. W., & Onofrei, D. Wave Motion, 48(6):515–524, 2011. arXiv: 1009.2038 Publisher: Elsevier B.V.
Paper doi abstract bibtex We cloak a region from a known incident wave by surrounding the region with three or more devices that cancel out the field in the cloaked region without significantly radiating waves. Since very little waves reach scatterers within the cloaked region, the scattered field is small and the scatterers are for all practical purposes undetectable. The devices are multipolar point sources that can be determined from Green's formula and an addition theorem for Hankel functions. The cloaking devices are exterior to the cloaked region. © 2011 Elsevier B.V.
