LIGHT SCATTERING BY A MULTILAYER CYLINDER IN THE WENTZEL-KRAMERS-BRILLOUIN APPROXIMATION
The formulas in the Wentzel-Kramers-Brillouin (WKB) approximation in scalar form for light scattering amplitude, extinction and absorption efficiency factors of multilayer circular cylinder illuminated by an incident light normally to cylinder’s axis are obtained. Numerical results of extinction and absorption efficiency factors for finite two-layered cylinder in the WKB approximation and infinite long two-layered cylinder (rigorous solution by separation of variables) are compared. The good agreement in the range of validity of the WKB approximation are obtained.
