  • 基于坐标变换理论,提出并推导了正N边形柱的隐身条件,并得到了相应隐身罩材料本构参数张量的通解表达式. 根据导出的本构参数张量,利用电磁仿真软件分别对N取不同值时的三个典型算例进行仿真验证. 仿真结果证实了所得到的本构参数张量的正确性. 考虑到损耗对于隐身效果的影响分析,这些分析结果为隐身物理机理的进一步理解,以及降低对称度隐身罩的设计奠定了理论基础.

     

    General expressions of constitutive tensors of the N-sided regular polygonal cylindrical cloaks are derived based on the coordinate transformation theory, then there are some full-wave simulations of the cloaks.The results of full-wave simulations validate the general expressions of constitutive tensors we derived. Furthermore, factors that degrade the cloaks invisibility are analyzed.
