The four different basis functions, Rao-Wilton-Glisson (RWG), TL, n × RWG and n × TL are used to define the planar triangles. The current distribution and the radar cross section (RCS) results are found to be more accurate for the TL and n × TL functions. TL and n × TL functions are used to improve the efficiency inspite of the increased computational cost.EnglishComputer simulationElectromagnetic wave scatteringFunctionsIntegral equationsMathematical operatorsMatrix algebraProblem solvingBasis functionsElectric-field integral equations (EFIE)Interaction expressionPlanar triangulationsMethod of momentsConference Paper10.1109/APS.2004.1332107
