Abstract

In this study, by using numerical simulations and scanning near-field optical microscopy, we investigate the excitation of HPhPs in MoO₃ with plasmonic nanoantennas. We find that the excitation efficiency is strongly dependent on the antenna length and orientation. By changing the size, shape and direction of the metal antenna, the excitation of the phonon Polariton mode can be controlled.
