Abstract: The scattering properties of the composite cylinders are discussed. Some integral equations are established, then the monent method is used to solve the surface currents under TM and TE polarization separately. After appropriate arrangement, the computer programs have been compiled general use. Finally, some calculation examples are given. The obtained resu-Its are compared with the published data. They are in good agreements. -
