用二阶微扰法计算了理想导电角波纹表面（平均为无限长圆柱体）的相干和非相干响应。一般的方法是应用消光定理写出表面电流密度的积分方程，然后用微扰理论求解，这些结果是用唯一的非平凡Pade近似来改写的。这种重铸产生了相当大的质量改进，至少在一个特殊情况下，被证明是定量的。>
The coherent and incoherent responses of perfectly conducting, angularly corrugated surfaces (which are infinite circular cylinders on the average) are calculated using a second-order perturbation method. The general approach used is to apply the extinction theorem to write an integral equation for the surface current density, and then to use perturbation theory to solve it. These results are recast by using the only nontrivial Pade approximant for this approximation. This recasting yield a considerable qualitative improvement which, at least in one special case, is shown to be quantitative as well. >
