Wideband Omnidirectional Microwave Cloaking

摘要

Scattering from electrically large objects invites discussions of Mie versus Rayleigh, shadows and diffraction, side scatter and backscatter. But one attribute remains infrequently discussed: forward or 'front" scatter. Antipodal transmission, the continuation of the transmitted wave with fidelity to the other side, is a puzzle posed by blockage and failure to find a way to fully propagate waves around it. If robust front scatter is possible, and the surface orientation is not prescriptive, the object itself becomes hidden, cloaked by the mirage of the environment on the other side. The object is invisible. Such a phenomenon is not a natural occurrence and requires new technology to approximate and achieve realization.
