Abstract

Lateral optical forces (LOFs) exerted on metamaterials typically arise from broken mirror symmetry in the system. In previous studies, we have demonstrated that, in addition to asymmetric particle or motif pairs, a periodic array of isosceles triangle motifs with carefully chosen shape can also exert large LOFs under plane wave illumination. In this study, we further explore this phenomenon systematically with consideration of thickness of the triangle motif. Results demonstrate new insight on how LOFs relate to the shape of triangle motifs.
