摘　　要：基于坐标变换理论,提出并推导了任意轴比下三维椭球的隐身条件,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不同轴比的三个典型算例进行仿真验证.仿真结果证实了所导出的本构参数张量的正确性.这些分析结果为隐身物理机理的进一步理解,以及三维隐身罩的设计奠定了更充分的理论基础.Arbitrary three-dimensional axiolitic cloaks are proposed and designed based on the coordinate transformation theory. The general expressions of constitutive tensors of the cloak are derived,and then some full-wave simulations of the cloaks based on the constitutive tensors that we derived are performed. The results of full-wave simulations validate the general expressions of constitutive tensors of the three-dimensional axiolitic cloaks.
