Abstract

A new 2D fast physical optics method is presented for computing the field diffracted by a conducting cylinder with arbitrary contour. This method produces a fast solution with uniform accuracy in all frequencies and incidence/observation angles. The method is a combination of different techniques such as path deformation, Morse theory, and Fourier LS continuation. The technique presented here is also valid and uniformly accurate near the caustic singularities produced by surface points with infinite curvature radius. This method also takes into account the endpoint contributions. © 2008 Wiley Periodicals, Inc.
