Studies on single scattering of electromagnetic waves by magnetic particles were reported in the 1980s by Kerker et al. [J. Opt. Soc. Am. 73, 765 (1983)] . They obtained that very small spherical particles with electric permittivity and magnetic permeability values such that ε = ( 4 μ ) ( 2 μ + 1 ) do not produce forward scattering. We show here that this condition contains an interesting exception at ( ε = 2 , μ = 2 ) when electric and magnetic resonances are present and around which the scattered field distribution is computed and described showing a polarization-insensitive behavior at the point ( ε = 2 , μ = 2 ).
