The results are validated against available reference models as well as compared to other numerical methods such as split step parabolic equation model and the method of moments.eninfo:eu-repo/semantics/closedAccessFast far-field approximation (FAFFA)groundwave propagationirregular terrainknife edgemethod of moments (MoM)split step parabolic equation (SSPE)two-ray (2Ray) modelArticleQ2Q11613691372WOS:000402127600015
