Abstract
Analytic approximations to the extinction efficiency, Q. for oriented and randomly oriented circular infinite cylinders based on anomalous diffraction is given. The results are compared with the exact code. These results are further generalized to randomly oriented elliptical cylinders. Using the formulae, Q. can be evaluated over E4 times infinity and 0 less than or equal to k less than or equal to 3, aspect ratios from 1 to 4 and modest to large particle sizes. The accuracy and limitations of this formula are discussed.
