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