Abstract
The forward scattering from an arbitrarily shaped cylinder is characterized by its induced field ratio (IFR). This paper describes how a focused beam system is used to determine the scattering characteristics of an arbitrary-shaped cylinder. The fields of the transmitting and receiving antennas, as well as the scattered field from the cylinder, are described by equivalent fundamental Gaussian beams. An analytical procedure based on the computation of the coupling between the Gaussian beams in the focused beam system is used to determine the IFR of the cylinder. The results obtained by this method verify well with the scattering characteristics computed analytically or numerically by the method of moments or finite-elements method.
