To speed up the numerical computation of beam shape coefficients in the generalized Lorenz–Mie theory (GLMT) for cylinders, a cylindrical localized approximation has recently been introduced [J. Opt. Soc. Am. A <b>14</b>, 3014 (1997)], in analogy with the localized approximation used for the GLMT for spheres. A rigorous justification of this cylindrical localized approximation is presented.
