Circuits Maxwell-Cattaneo Heat Waves Scattering Cancellation-based Cloaking

Mohamed Farhat, et al., "Scattering Cancellation-based Cloaking for the Maxwell-Cattaneo Heat Waves". Physical Review Applied, 11(4), 2019, 044089. We theoretically propose scattering cancellation-based cloaks for heat waves that obey the Maxwell-Cattaneo equation. The proposed cloaks possess carefully tailored diffusivity to cancel the dipole scattering from the object that they surround, and thus can render a small object invisible in the near and far fields, as demonstrated by full-wave finite-element simulations. Mantle heat cloaking is further analyzed and proposed to simplify the design
