Abstract

Radiation of an arbitrarily oriented dipole and its scattering from a long nite circular cylinder is determined.Cylinder of perfect electric conductor, impedance and perfect electromagnetic conductor has been considered for the analysis. An approximate method has been proposed and utilized to obtain the solution.The approximate method consists of two main steps. In the rst step, the current distribution on the in nite length cylinder is determined.Then the portions of the in nite cylinder above and below certain nite length are removed with the assumption that the current on the remaining portion of the cylinder is unchanged. Hence by utilizing this current distribution corresponding to in nite cylinder, eld due to a long nite cylinder has been obtained.This approximation is valid analytically if the cylinder is very long as compared to its radius. Numerical results have been validated by comparing with the published literature under some special conditions and are found in good agreement with them.
