Abstract
A uniform line integral representation is derived for edge-diffracted fields by using the modified theory of physical optics and uniform asymptotic evaluation methods. The method is applied to the problem of diffraction of plane waves by a semi-infinite edge, which creates tip-diffracted fields with edge-diffracted waves. The uniform diffracted fields are plotted and examined numerically.
摘要
通过使用修正的物理光学理论和一致渐近评估方法，推导出了边缘衍射场的统一线积分表示。该方法应用于平面波被半无限边缘衍射的问题，该边缘产生带有边缘衍射波的尖点衍射场。绘制了统一衍射场并进行了数值检验。
