On the calculation of potential integrals for linear source distributions on triangular domains

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.
