Radiation of an arbitrarily oriented dipole and its scattering from a long finite circular cylinder is determined. Cylinder of perfect electric conductor, impedance and perfect electromagnetic conductor has been considered for the analysis. An approxi- mate method has been proposed and utilized to obtain the solution. The approximate method consists of two main steps. In the first step, the current distribution on the infinite length cylinder is determined. Then the portions of the infinite cylinder above and below certain finite 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 infinite cylinder, field due to a long finite 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.
