Abstract

Lateral optical forces (LOFs) exerted on metamaterials typically arise from the broken mirror symmetry in the system. It has been reported that a repeated pair of particles or circular motifs with different sizes or refractive indices can generate LOFs. Studies show that an optimised LOF could be large enough to manipulate the structure moving at a macroscopic scale. We demonstrate that this force can also be generated by a repeated single triangle motif. By adjusting the size and shape of the triangle, we can control the magnitude and direction of the LOF. The optimised structure parameters can be found by optimisation routines such as Bayesian optimisation combined with optical force calculation methods such as rigorous coupled-wave analysis.
