Three different methods can be used to numerically compute the g(n) coefficients in the generalized Lorenz-Mie theory. Two of them are rigorous and involve (i) numerical evaluation of quadratures andâ€¦ (More)

Recently a so-called standard beam description of Gaussian beams was introduced [J. Opt. Soc. Am. A 11, 2503 (1994)]. However, it was afterward observed [Appl. Opt.35, 2702 (1996)] that thisâ€¦ (More)

The forward scattering of a Gaussian laser beam by a spherical particle located along the beam axis is analyzed with the generalized Lorenz-Mie theory (GLMT) and with diffraction theory.â€¦ (More)
