What is it about?
Thermal diffusion and optical propagation usually appear as strongly different processes. However deep analogies can be emphasized between heat conduction and metal optics. Such analogies allow us to analyze to which extent optical concepts can be generalized to the field of thermal. Here we address the cases of multilayer design, microcavities, diffraction, metamaterials and cloaking.

Why is it important?
It is shown how the same computer codes can be used for both metal optics and heat conduction, with straightforward modifications in the input data. Results concern photonic cristals and metamaterials, microcavities, diffraction and cloaking.
Perspectives
This paper is mainly focused onto a planar geometry. Generalization to arbitrary shape & anisotropy & heterogeneity would follow. A significant number of concepts remains to be explored.
