Abstract :
A particle scattering in close proximity to an anisotropic substrate can experience a repulsive force if one of the diagonal components of the permittivity tensor is close to zero. We derive a condition for this repulsive force and show its broad bandwidth for realistic metamaterial substrates, including those based on graphene multilayers.
