Bridging the Gap Between the Rayleigh and Thomson Limits for Various Convex Bodies
Abstract
It is well known that the Rayleigh approximation to extinction, scattering and absorption efficiencies for spheres is limited to small size parameters, x, and small values of mix, where m is the complex index of refraction. It is also known that the Thomson approximation to these same efficiencies is valid for small x and m = Do. We have established an exact transform of the Mie coefficients, for both spheres and infinite cylinders, that removes the m related restrictions of the Rayleigh and Thomson approximations. The resulting series for spheres and infinite cylinders are valid for all m and small x. This transform can also be applied in an approximate form to spheroids.
