• scattering; Mie particle; Introduction The original Kerker scattering of zero backward scattering was first proposed for homogeneous magnetic spheres with equal electric permittivity and magnetic permeability ε = μ [1]. This proposal had not attracted much attention for a long time, mainly due to the
