Electric and magnetic dipolar response of Germanium spheres: Interference effects, scattering anisotropy and optical forces
We address the scattering cross sections, and their consequences, for
submicrometer Germanium spheres. It is shown that there is a wide window in the
near infrared where light scattering by these particles is fully described by
their induced electric and magnetic dipoles. In this way, we observe remarkable
anisotropic scattering angular distributions, as well as zero forward or
backward scattered intensities, which until recently was theoretically
demonstrated only for hypothetically postulated magnetodielectric spheres.
Also, interesting new effects of the optical forces exerted on these objects
are now obtained.Comment: 13 pages, 4 figure
