Active thermal cloaking and mimicking

Abstract: We show how to hide objects or sources by using an active source and dipole distribution on a surface enclosing the region to be cloaked, allowing for cloaking even in transient regimes. This technique does assume a homogeneous medium and knowledge of the probing field, but applies to a variety of physical phenomena that can be modeled by the heat equation (including mass or light diffusion). The same idea can be used to make an object (or source) appear as another one. This is work in collaboration with Maxence Cassier, Trent DeGiovanni and Sebastien Guenneau.
