摘要

本文利用物理光学积分的高频渐近计算方法，对横磁极化情况下的导体圆柱散射场进行了估计。采用最陡下降路径法估计散射辐射积分。本文还提出了一种近似方法来估计正向附近的远场散射。将渐近结果与数值积分法和精确特征函数展开解的结果进行了比较。

High Frequency Asymptotic Evaluation of PO Integral for EM Scattering from PEC Circular Cylinder

In this paper, the scattering field from a circular conducting cylinder has been estimated by the high frequency asymptotic evaluation of physical optics (PO) integral for the case of transverse magnetic (TM) polarization. The steepest descent path (SDP) method has been used to estimate the scattering radiation integral. An approximation has also been proposed to estimate the scattering far field at the vicinity of the forward direction. The asymptotic results are compared with those by numerical integration method and the exact eigenfunction expansion solution.
