Diffraction at a strip with one face soft (electric) and the other hard (magnetic) is studied. New results obtained by the method of moments (MoM) are compared with the asymptotic theory of edge diffraction (TED) for the totally soft and hard strips. Attention is given to diffraction of oblique incident waves including the grazing diffraction. Novel analytic estimations for the forward and backward grazing scattering are established via the advanced physical theory of diffraction (PTD) free of grazing singularities. These estimations are demonstrated for the infinitely long strips and finite size rectangular plates.

软硬板条上的双基地散射:矩量法(MoM),边缘衍射理论(TED)和衍射物理理论(PTD)分析

研究了在一个面为软(电)面而另一面为硬(磁)面的条带上的衍射。通过矩量法(MoM)获得的新结果与完全软带和硬带的边缘衍射渐近理论(TED)进行了比较。注意包括掠射衍射在内的斜入射波的衍射。通过先进的无衍射奇异衍射物理理论(PTD),建立了前向和后向掠射散射的新型解析估计。这些估计是针对无限长的条带和有限尺寸的矩形板而论证的。
