  We reveal that an isotropic homogeneous subwavelength particle with a high
refractive index can produce ultra-weak total scattering due to vanishing
contribution of the electric dipole moment. This effect can be explained with
the help of the Fano resonance and scattering efficiency associated with the
excitation of an anapole mode. The latter is a nonradiative mode emerging from
destructive interference of electric and toroidal dipole moments, and it can be
employed for a design of highly transparent optical materials.
