Electromagnetic scattering from perfectly conducting cylinders with electrically large cross sections

The integral equation for scattering by an aggregate of perfectly conducting cylinders, the sum of their perimeters being well over 120 wavelength and each cylinder being of arbitrary cross section, are first developed and then solved by means of the method of moment (MM) to give the current distribution induced on the scatterer surfaces, the scattering cross section versus azimuthal angle for both parallel and perpendicular polarized incident waves. The validity of the computer program has been verified by comparing results of interchanging the direction of incidence and the direction of observation due to the reciprocity theorem that the observed scattered field and the cross section is unchanged if the transmitter and receiver are interchanged.
