In this paper, a new method to solve the electromagnetic shielding problem of cylindrical thin shell with arbitrary cross-section is given. Based on the average boundary conditions and using the discontinuity theorem of vector derivative of single-layer scalar wave function, Integral equations for the electromagnetic shielding problem of thin shell are obtained.The boundary integral method is used to solve the integral equations and the results are in good agreement with the solutions under the exact boundary conditions.The method in this article is simple and easy , Sufficient to accurately describe the distribution of electromagnetic fields on both sides of the cylindrical thin shell
