论文摘要
在近似近似中提出了经典尖锐衍射理论的一般重新制定。众所周知的庞加莱矢量电位结构直接在菲涅尔的2D积分内采用，以便将其转换为孔径边界上的单个1D轮廓积分。与最近开发的BDW理论重新审核的不同，这种方法可以应用于任意形状形状形状的尖角平面孔径的任意波场分布。提出了一些有趣的示例。
A general reformulation of classical sharp-edge diffraction theory is proposed within paraxial approximation. The, not so much known, Poincaré vector potential construction is employed directly inside Fresnel's 2D integral in order for it to be converted into a single 1D contour integral over the aperture boundary. Differently from the recently developed paraxial revisitation of BDW's theory, such approach can be applied to arbitrary wavefield distributions impinging onto arbitrarily shaped sharp-edge planar apertures. A couple of interesting examples of application of the proposed method is presented.
