  We describe a method to control the directional scattering of a high index
dielectric nanosphere, which utilizes the unique focusing properties of an
azimuthally polarized phase vortex and a radially polarized beam to
independently excite insde the nanosphere a spinning magnetic dipole and a
linearly polarized electric dipole mode normal to the magnetic dipole. We show
that by simply adjusting the phase and amplitude of the field on the exit pupil
of the optical system, the scattering of the nanosphere can be tuned to any
direction within a plane and the method works over a broad wavelength range.
