摘要
Numerical computations in the framework of the generalized Lorenz-Mie theory require the evaluation of a new double set of coefficients (FORMULA PRESENT). A localized interpretation of these coefficients is designed to permit fast and accurate computations, even on microcomputers. When the scatter center is located on the axis of the beam, a previously published localized approximation for a simpler set of coefficients gn is recovered as a special case. The subscript n in coefficients gn and gm is associated with ray localization and discretization of space in directions perpendicular to the beam axis, while superscript m in coefficients gm is associated with azimuthal wave modes. © 1990 Optical Society of America.
