Abstract

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=(4μ)(2μ+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).
