High-frequency scattering from a semi-infinite cylindrical resistive pipe

Abstract

An asymptotic high-frequency solution Is presented for the problem of scattering of electromagnetic waves emanating from a ring source by a semi-infinite cylindrical pipe by using the Wiener-Hopf technique. The pipe is modelled with resistive boundary conditions corresponding to a thin dielectric or a thin conductor with finite conductivity. The effects of the pipe radius and the resistivity on the total scattered field are also illustrated.
