  Spin-orbit interactions of light are ubiquitous in multiple branches of
nanophotonics, including optical wave localization. In that framework, it is
widely accepted that circularly polarized beams lead to spin-dependent apparent
shifts of dipolar targets commonly referred to as optical mirages. In contrast,
these optical mirages vanish when the illumination comes from a spinless beam
such as a linearly polarized wave. Here we show that optical localization
errors emerge for particles sustaining electric and magnetic dipolar response
under the illumination of spinless beams. As an example, we calculate the
optical mirage for the scattering by a high refractive index nanosphere under
the illumination of a linearly polarized plane wave carrying null spin,
orbital, and total angular momentum. Our results point to an overlooked
interference between the electric and magnetic dipoles rather than the
spin-orbit interactions of light as the origin for the tilted position of the
nanosphere.
