Fast Converging Graded Mesh for Bodies of Revolution with Tip Singularities

Abstract

In this paper, we study the plane wave scattering from perfectly electric conducting (PEC) bodies of revolution (BOR) with tip singularities. It is known that solutions to surface integral equations such as magnetic, electric, and combined field integral equations (MFIE, EFIE, and CFIE, respectively) are singular near the tips. Consequently, the convergence of method of moments (MoM) based on those surface integral equations is not optimal or guaranteed. By using appropriate graded meshes, one can retain the optimal convergence rate in MoM.
