It represents a combination of the fundamental PTD concept of fringe currents and the method of moments (MoM). The objects in the vicinity of edges are considered as parts of appropriate tangential wedges. Integral equations are formulated for fringe currents on these wedges and solved by the MoM. Then, a far field radiated by these currents is calculated. A very good agreement is observed with the field produced by the currents induced on the actual scattering object when its size exceeds a few wavelengths.eninfo:eu-repo/semantics/closedAccessDiffractionfringe wavesmethod of moments (MoM)physical optics (PO)physical theory of diffraction (PTD)polygonal cylindersrounded wedgescattering cross sectionscattered far fieldsoft boundary conditionArticleQ2Q11625902593WOS:000409080800025
