Query: Optomechanical manipulation with hyperbolic metasurfaces   Auxiliary nanostructures introduce additional flexibility into optomechanical
manipulation schemes. Metamaterials and metasurfaces capable to control
electromagnetic interactions at the near-field regions are especially
beneficial for achieving improved spatial localization of particles, reducing
laser powers required for trapping, and for tailoring directivity of optical
forces. Here, optical forces acting on small particles situated next to
anisotropic substrates, are investigated. A special class of hyperbolic
metasurfaces is considered in details and is shown to be beneficial for
achieving strong optical pulling forces in a broad spectral range. Spectral
decomposition of the Green functions enables identifying contributions of
different interaction channels and underlines the importance of the hyperbolic
dispersion regime, which plays the key role in optomechanical interactions.
Homogenised model of the hyperbolic metasurface is compared to its
metal-dielectric multilayer realizations and is shown to predict the
optomechanical behaviour under certain conditions related to composition of the
top layer of the structure and its periodicity. Optomechanical metasurfaces
open a venue for future fundamental investigations and a range of practical
applications, where accurate control over mechanical motion of small objects is
required.
