摘　　要：基于坐标变换理论推导了任意多棱柱隐身罩的隐身条件,并得到了相应隐身罩材料参数的张量表达式。根据导出的材料参数的张量表达式,通过全波仿真分别对三棱柱、四棱柱和六棱柱隐身罩进行了仿真验证,仿真结果证实了所得材料参数张量表达式的正确性;利用所推公式设计的隐身罩的确能够控制电磁波绕着内部被隐物体传播,并使波离开隐身罩时恢复成原来的传播方向,从而成功地将内部物体隐身。Based on the coordinate transformation theory, the condition for irregular prism cloaks is deduced and the tensor expressions of electromagnetic parameters are obtained. By using the deduced tensor expressions of electromagnetic parameters, the effects of 3 - sided, 4 - sided and 6 - sided prism cloaks are verified through full - wave simulations. The results confirm the validity of the tensor expressions of electromagnetic parameters obtained. The cloaks designed by using the deduced expressions can surely make the electromagnetic wave transmit around the in- ner object and resume its primary transmission direction. The work done in this paper provided a theoretical basis for the design of two - dimensional baroque cloak.
