Mohamed Farhat, et al., "Cloaking through cancellation of diffusive wave scattering." Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences 472, 2016, 20160276. A new cloaking mechanism, which makes enclosed objects invisible to diffusive photon density waves, is proposed. First, diffusive scattering from a basic core–shell geometry, which represents the cloaked structure, is studied. The conditions of scattering cancellation in a quasi-static scattering regime are derived. These allow for tailoring the diffusivity constant of the shell enclosing the object so
