Galerkin versus razor-blade testing in the method of moments formulation for multiconductor transmission lines
In this paper, the effect of the testing technique in the method of moments (MoM) solution for multiconductor transmission lines is investigated. Two important testing techniques, namely, Galerkin and razor-blade testing, are used and compared. The problem is formulated using the mixed potential integral equation. The analysis shows that the solution of the longitudinal modal current near the edge of the conductor is significantly affected by the testing scheme in the MoM kernel. For the selected expansion functions, razor-blade testing gives more reasonable modal current distribution than Galerkin testing. (C) 2000 John Wiley & Sons, Inc.
