Quasi-Ray Gaussian Beam Algorithm for Time-Harmonic Two-Dimensional Scattering by Moderately Rough Interfaces

Abstract

Gabor-based Gaussian beam (GB) algorithms, in conjunction with the complex source point (CSP) method for generating beam-like wave objects, have found application in a variety of high-frequency wave propagation and diffraction scenarios. Of special interest for efficient numerical implementation is the noncollimated narrow-waisted species of GB, which… (More)
