  In this work 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
and bring this cloaking technology one step closer to its practical
implementation, with promising applications in nanoelectronics and defense
related applications.
