A Toroidal Harmonic Representation of the Yukawa-potential Kernel for a Circular Cylindrical SourceJerry P. Selvaggi, Sheppard J. Salon, and M. V. K. Chari doi:10.2529/PIERS071206060403 Downloads: 752 Abstract:A true cylindrical series expansion of the Yukawa- or screened Coulomb-otential kernel is developed for a finite circular cylindrical source through the application of a toroidal harmonic expansion. The Yukawa kernel is separated into a singular and nonsingular part. The singular part is expanded in terms of the associated toroidal harmonics and the nonsingular part is expanded in terms of an elementary binomial expansion.References:1. Liu, B. and J.
