Analysis of the electromagnetic scattering of rivets on the conducting plate

In this paper, the electric field integral equation (EFIE) in conjunction with the moment method is used to analyze the electromagnetic scattering problem of rivets on the conducting plate. The surfaces of the rivets and the plate are partitioned into triangular cells, the current distribution on the patches is represented by a subdomain-type basis function, the EFIE is translated into a matrix equation by the Galerkin method, then the current coefficient is obtained. Results show the properties of RCS varying with the incident angle when there are rivets on the plate. Furthermore, we can see the effect of rivets on RCS.
