摘要：

Wave cloaking, concentrating and ghosting have long captivated the popular conjecture and attracted intensive research in various communities of wave dynamics, e.g., optics, electromagnetics, acoustics, etc. However, their inhomogeneous and extreme parameters imposed by transformation-optic method will usually require challenging realization with metamaterials, resulting in narrow bandwidth, loss, polarization-dependence, etc. We proposed to use natural and homogeneous thermal materials for the demonstration of heat cloaking, concentration and ghosting. Practical realization and experimental verification of such homogeneous thermal devices are suggested and validated by using two naturally occurring conductive materials, which provides an unprecedentedly plausible way to flexibly guide and redistribute the heat flow.
