The SA-BiCGSTAB method is applied over rough terrain profiles as well as re-entrant surfaces which can not be handled by any conventional stationary iterative technique.EnglishComputational methodsDiffractionIntegral equationsIterative methodsMethod of momentsProblem solvingBiConjugate Gradient Stabilized (BiCGSTAB)Forward-Backward method (FBM)Multiple- diffraction (MD)Spectral acceleration (SA)Electromagnetic wave propagationConference Paper10.1109/MMET.2004.1397117
