| 摘 要： | 基于坐标变换理论设计了菱形、不规则四边形和扇形隐形斗篷。利用COMSOL Mul-tiphysics对其进行仿真得到,覆盖斗篷后电磁场可以＂拐弯＂绕着物体走,斗篷内部区域未受到电磁场干扰,隐形效果均得到了较好的证实。这三种形状的隐形斗篷比圆柱形和球形斗篷更为常见,因而在减少物体的雷达散射截面（RCS）方面具有更为广泛的实用性。

| Abstract: | Diamond,irregular quadrilateral and fan shaped invisible cloaks are proposed in this paper based on the coordinate transformation theory.Through COMSOL Multiphysics simulation,it can be seen that the electromagnetic wave inside can ＂bend＂ around the objects and will not interfere with the inner region of the cloaks,which means that they have relatively good invisibility effect.In real world these three invisible cloaks are more common than cylinder and sphere shaped cloaks,thus being more practical in reducing the radio cross-section（RCS） of many objects. |
