Fast physical optics method for very large parabolic PEC surfaces with polygonal contour
Abstract:
This paper shows a 3D fast physical optics method for computing the backscattered field of a parabolic surface with polygonal contour. The Path deformation technique is used to convert the highly oscillatory PO integral into a slow varying function. A Gaussian quadrature with a number of sample points no frequency dependent is used to compute the integral.
