Heat flux and temperature field cloaks for arbitrarily shaped objects

Abstract

We apply transformation optics (TO) theory to investigate two-dimensional heat flux cloaks for arbitrarily shaped objects. The TO theory is applied to design a device through which heat flux travels around objects with arbitrary shapes, which greatly improves the flexibility of the cloak applications. The proposed theory is verified by numerical results, showing that the proposed method is capable of controlling the diffusive heat flow and cloaking a region with arbitrary geometries of interest.
