Experimental investigation of omnidirectional multiphysics bilayer invisibility cloak with anisotropic geometry 下载免费PDF全文
Thermal-electric bilayer invisibility cloak can prevent the heat flux and electric current from touching the object without distorting the external temperature and electric potential fields simultaneously. In this paper, we design an omnidirectional thermal-electric invisibility cloak with anisotropic geometry. Based on the theory of neutral inclusion, the anisotropic effective thermal and electric conductivities of confocal elliptical bilayer core–shell structure are derived, thus obtaining the... 相似文献
