For an infinitely long circular cylinder, the solution of the light scattering problem for the perpendicular incidence was first derived by Rayleigh [ 418 ] who returned to this problem once again in his last work [ 417 ] written a short time before his death. The problem for oblique incidence was solved in 1955 by J.R. Wait [ 491 ] (Kerker [ 274 ] at p.256 mentions also the paper of Blank, 1955); a bit later the same result was obtained in [ 172 ]). ...
