论文摘要
讨论并分类了纳米粒子在谐振光散射处的po矢量场的奇异性。结果表明，它们有两种通用类型，即（i）与奇异点处的磁性（和/或电场）磁场消失有关的奇异性，以及（ii）与奇异点附近的站立波形成相关的奇异性。这些类型的奇异性与奇异点的拓扑结合和空间维度（3D vs. 2d）的连接得以揭示。
Singularities of the Poynting vector field at resonant light scattering by nanoparticles are discussed and classified. It is shown that there are two generic types of them, namely (i) the singularities related to the vanishing of the magnetic (and/or electric) field at the singular points and (ii) the singularities related to the formation of standing waves in the proximity of the singular points. The connection of these types of singularities to the topology of the singular points and the space dimension (3D vs. 2D) is revealed.
