| Abstract: | In this paper, a simplified electromagnetic shielding theory which is sufficient for the engineering requirements is presented and an integral equation of the electromagnetic shielding problem for arbitrarily shaped shells is derived. We then solve the integral equation for the surface current density by the moment method and obtain the electrical fields in the shielding shells by the scattering theory. Therefore, the electromagnetic shielding effectiveness is achieved. A computer program (by FORTRAN language) for shielding shells of various shapes are also offered. The optimal shielding frequency, "no-shielding" frequency and other important properties are found out. |
