中文摘要	a new finite difference wide-angle beam propagation method is developed by introducing the least-squares expansion approximant in the propagator expansion. in this new method it is not necessary to select the reference index point because of the whole region approaching the lease-square expansion. this method avoids the problems induced by error selection of the reference index in the old methods based on taylor or pade expansion. several typical structures are simulated by the new method and the results prove the validity of it.
