Tuning Surface Phonon Polaritons in One‐Dimensional Complementary Nanostructures via Curvature and Dielectric

Advanced Photonics Research, EarlyView.
Curvature and dielectric is introduced to tune properties of surface phonon polaritons (SPhPs) in complementary nanostructures: nanowire (NW) and nanohole (NH). It is found that NH complements the frequency band range of SPhP of NW. Frequency‐band subinterval of the SPhP in NHs and NWs can be tuned by dielectric.
