The Scattering of an Electromagnetic Wave by a Semi-Infinite Conducting Cylinder Capped by a Conducting Hemisphere in the Long Wavelength Limit

Abstract : The scattering problem differs from the usual long wavelength limit scattering problem--called the Rayleigh scattering problem--in an essential aspect. In the present paper the wavelength lamda is large compared to the radius a, that is ka is small compared to unity. Of course, since the cylinder is semi-infinite, lamda is small compared to the length of the scatterer. In Rayleigh scattering, by contrast, all linear dimensions of the scatterer are small compared to the wavelength.
