摘　　要：从阐述麦克斯韦方程组在坐标变换下形式不变性出发,介绍了基于变换光学设计隐身衣的思路,并分别推导了实现二维圆柱形、椭圆柱形、正方形隐身衣的相对介电常量和相对磁导率张量在物理空间的分布公式.利用COMSOL Multiphysics仿真软件,给出了二维圆柱形、椭圆柱形、正方形隐身衣的隐身效果.Starting from the form invariance of Maxwell’s equations under coordinate transformation,the design idea of invisibility cloak based on transformation optics was introduced.The physical-space distribution formulas of dielectric constant and permeability tensor needed to realize two dimensional cylindrical,elliptical cylindrical and square invisibles were derived,respectively.Using the derived formulas of dielectric constant and permeability and the COMSOL Multiphysics simulation software,the stealth effects of these two dimensional cylindrical,elliptical cylindrical and square invisibility cloaks were given.
