我们推导出一个近似但严格的二维电磁隐身壳，其中没有参数是奇异的。材料参数的简单性使其在实践中比其他隐形解决方案更容易实现。该壳的分析公式还提供了其散射减少性能、相对于内部尺寸的厚度以及所需介电常数和磁导率的复杂性和实现难度之间的简单而明确的分析权衡。
We derive an approximate but rigorous two dimensional electromagnetic cloaking shell in which no parameters are singular. The simplicity of the material parameters makes it potentially easier to realize in practice than other cloaking solutions. The analytical formulation of this shell also provides a simple and explicit analytical trade-off between its scatter reduction performance, its thickness relative to the interior size, and the complexity and realization difficulty of the required permittivity and permeability.
