Heat flow with thermal metamaterials

Abstract : Analogies between thermal diffusion and optical propagation in metal optics [1] allowed to generalize transformation optics [2,3] to the field of thermal [4-7], hence expanding cloaking and mimicking principles to thermodynamics. As a result, thermal metamaterials supported on homogenization techniques have been emphasized for the management of heat flow. In this talk we first present our recent work on thermal metamaterials, including theoretical, numerical and technological aspects. Realistic applications are discussed within the framework of given objects to cloak or mimic. Heat conduction and thermal radiation are considered. The second part of the talk concerns the design of metamaterials. Homogenization and singular perturbations problems in stratified media have been studied in [8,9]. These results are revisited and extended in the setting of both the heat equation and the equations of linear elasticity.
