Dual-function thermoelastic cloak based on coordinate transformation theory

In past years, various cloaks have attracted the attention of many scientists but they usually remain confined to a single function. Cloaks combining multiple functions, however, are desirable. this paper, we design thermoelastic with dual functionality by coordinate transformation technique. The wave equations for cloaking and explicit expressions required material parameters established. Symmetrization elastic tensor is applied using Norris’ gauge matrix emphasize feasibility designs. Two different operating conditions, transient propagation steady heat transfer, adopted in numerical calculations designed cloaks. It shown that, on one hand, from perspective observer, whether cloak symmetrized or not, its external response identical invisibility reliable. On other it destined that symmetrization would be accompanied increase internal displacement, which may need paid actual design. addition, temperature effects both consistent. work paper pave way toward realization cloaks, thus broadening research scope metamaterials.
