Abstract

Present analytical formulas for the singular field contributions of linear source distributions on triangular domains. The formulas can be used for near-field calculations of electric and magnetic source currents, especially for the calculation of method of moments (MOM) matrix elements due to the solution of surface integral equations. For MOM self-coupling terms involving the scalar Green function of free space, the authors present expressions comprising analytical solutions of both the source integrals and the testing integrals
