We have developed a modified Arnoldi method that includes a complex square-root
approximation, which excels at modeling the propagation of highly diverging
beams in various media. Simulations of one transverse dimensional beam with
an ultranarrow width and of cylindrical Gaussian beams with various divergence
angles reveal the strength of this nonparaxial-beam propagation method.
