新型椭圆形互补隐身斗篷设计

摘要

A novel elliptical complementary invisible cloak is designed based on the transformation optics and the comple-mentary media theory. The constitutive parameter tensor expressions have been obtained. The results of full-wave simulations by using finite-element software confirm the validity of the constitutive parameter tensor expressions. This invisible cloak can not only hide the objects inside the cloak, but also permit the electromagnetic wave penetrate into the cloak and communicate with the outside world.%基于变换光学理论和互补媒质理论，提出了新型椭圆形互补隐身斗篷的设计方法，并得到了本构参数张量表达式。利用基于有限元算法的电磁仿真软件对该模型进行了全波仿真验证，结果证实了所得到的表达式的正确性。这种隐身斗篷不仅能够实现对位于其内部的物体隐身，而且电磁波能透进隐身斗篷内部进而可以与外界进行通信。
