Abstract
The localized surface plasmon resonance (LSPR) of metal nanoantenna is significantly influenced by the size, shape, and environment but also its substrate. Here, we have used the epsilon-near-zero (ENZ) feature of hyperbolic metamaterial (HMM) as a substrate to manipulate the resonance of plasmonic nanoantennas. We demonstrate that the vanishing index of the substrate slows down the resonance shift of the antenna, known as pinning effect. Moreover, we have controlled the pinning effect at different regions by tuning the ENZ wavelength of HMM. This can be used for better manipulation of plasmonic structures used in flat optics and biosensing applications.
