Abstract
The problem of diffraction from a perfectly conducting wedge is examined with the modified theory of physical optics (MTPO). The exact wedge diffraction coefficient is compared with the asymptotic edge waves of MTPO integral and related surface currents are evaluated. The scattered electric fields are expressed by using these current components. The total, incident and reflected diffracted fields are compared with the exact series solution of the wedge problem, numerically.
摘要
利用修正的物理光学理论（MTPO）研究了理想导电楔体的衍射问题。将精确的楔体衍射系数与MTPO积分的渐近边缘波进行了比较，并评估了相关的表面电流。利用这些电流分量来表示散射电场。通过数值计算，将总场、入射场和反射衍射场与楔体问题的精确级数解进行了比较。
