  • 基于变换光学理论设计了椭圆形散射转移斗篷,并推导了相应的本构参数张量表达式, 根据得到的本构参数,利用基于有限元算法的软件分别对椭圆形介质柱、导体柱进行了全波仿真验证. 仿真结果证实了所得本构参数的正确性,验证了散射转移斗篷可以模拟任意物体, 包括介质、导体的幻象,这些结果为设计隐身斗篷提供了一种新的理论途径.

     

    Based on transformation optics theory, an elliptical scattering-shifting cloak is designed and the constitutive parameter tensor expressions are derived. Then full-wave simulations to mimic the ellptical dielectric and conductor cylinder are obtained by using finite-element software. The results of full-wave simulations validate the constitutive parameter tensors we derived and verify that the scattering-shifting cloak can imitate any object including dielectric and conductor: these results provide a new theoretical approach to design cloaks.
