Numerical results in the form of current and path loss are presented and compared with previously published as well as measured results in order to assess the accuracy and efficiency of this method.EnglishBiconjugate gradient stabilized methodElectromagnetic rough-surface scatteringPropagation over terrainSpectral accelerationAccelerationElectric current distributionElectric currentsElectric impedanceElectromagnetic wavesGeometrical opticsGreen's functionIntegral equationsIterative methodsLight propagationMethod of momentsTwo dimensionalLight scatteringArticle10.1002/mop.209301098-2760
