[OMC10-02] Plasmonic nanogap optical vortex excitation via spin-to-orbital angular momentum conversion

*Christophe Pin¹, Keiji Sasaki¹ (1. Hokkaido University, RIES)

In this study, we design a hexamer nanoantenna composed of gold nanorods with a periodic tilt and numerically analyze the excitation efficiency of the nanogap quadrupole mode under circularly polarized plane wave irradiation.
