Scattering of a vector Bessel vortex beam by a charged sphere

On an infinite number of quadratures to evaluate beam shape coefficients in generalized Lorenz-Mie theory and the extended boundary condition method for structured EM beams

“…[30] or (ii) evaluating the BSCs of each plane wave and summing up to obtain the BSCs of the whole beam, before entering GLMT computations,e.g. without pretending to exhaustiveness [31], [32], [33], [34], [35], [36], [37], [38], [39] and [40] for a variant relying on the use of a Whittaker integral formalism. See also [41] for the relationship between BSCs and plane wave spectra.…”
