Least-Square Iterative Technique for Solving Time-Domain Scattering Problems

摘要

An alternative method for the numerical solution of time-domain integral equations pertaining to three-dimensional, transient scattering problems is developed and applied to two representative acoustic scattering configurations. It is based on the iterative minimization of an integrated square error. For the cases considered, the method gives more accurate results than the frequently used 'marching-on-in-time' method (within comparable computation times).
