Web22 mei 2013 · We unveil the relationship between two anomalous scattering processes known as Kerker conditions and the duality symmetry of Maxwell equations. We generalize these conditions and show that they can be applied to any particle with cylindrical symmetry, not only to spherical particles as the original Kerker conditions were derived for. We also … WebIn contrast to the ﬁrst Kerker condition, the zero optical scattering condition in the forward direction, given for dipolar particles by a 1 = b 1, is precluded by the optical theorem for lossless spheres [41–43].
