The minimization of the back scattering of a cylinder by central loading

A theoretical and experimental study of the minimization of the back scattering by a thin cylinder by central loading is presented. The induced current on a centrally loaded cylinder illuminated by a plane wave at normal incidence was determined theoretically and experimentally. The magnitude and phase of the induced current can be greatly changed by a central impedance. The optimum loading to achieve zero back scatter in the broadside direction from a thin cylinder shorter than two wavelengths and the optimum central impedance for the purpose of minimizing the broadside back scattering from a thin cylinder over a wide range of frequencies has been determined.
