Our notations follow Kerker exactly The Scattering of Light and Other Electromagnetic RadiationAcademic, New York, 1969); H. C. van de Hulst, Light Scattering by Small Particles (Wiley, New York, 1957), except for the spherical Bessel functions noted jn by Kerker and van de Hulst while we have chosen Ψn1 like L. Robin, Fonctions Sphériques de Legendre et Fonctions Sphéroidales (Gauthiers-Villars, Paris, 1959), Vol. 3.
In Refs. 2 and 3, the beam is modeled using a series expansion of the potential vector. The L order (L for lowest) is the lowest order complying with Maxwell’s equations. The L− order is lower than the L order since only the first terms of the series are kept. For example, the basic radial function f is, respectively, f = Ψ0 at order L− and f = Ψ0(1 − 2Qrcosθ/l) at order L. Ψ0 being the well-known Fundamental mode of Gaussian beams: Ψ0=iQ exp(-iQr2 sin2θ/w02) where l is the so-called diffraction or spreading length of the beam, w0 is the beam radius at the waist, and Q = 1/(i+2r cosθ/l).
