However, this approach is not effective in the improvement in the computational efficiency achieved for three-dimensional geometries in planar layered media. In this paper, discussed are the difficulties involved in using the spatial domain, closed-form Green's functions in the Method of Moments formulation for three-dimensional geometries and proposed a technique to improve the computational efficiency of the MoM.EnglishApproximation theoryCalculationsConvergence of numerical methodsElectromagnetic wavesGeometryIntegral equationsIntegrationMathematical transformationsMatrix algebraThree dimensionalGreens functionsMethod of momentsMixed potential integral equationPlanar microstrip geometriesThree dimensional problemsTransient responseFunction evaluationConference Paper10.1109/APS.1994.407838
