Abstract

A new method of solution for the electromagnetic shielding problems of a thin cylindrical shell of arbitrary cross section is presented. On the basis of averaged boundary conditions, we use the theorem of discontinuity of the normal derivative of a single-layer potential, integral equations of electromagnetic shielding for the thin cylindrical shell of arbitrary cross section are derived, and they are solved by using the method of boundary element. Compared with the solution obtained by using precise boundary conditions, the method presented is very simple and convenient. A foundation is laid for simple calculation of the electromagnetic fields from two sides out of the thin cylindrical shell and its shielding effectiveness.
