Light-matter interaction control with epsilon-near-zero metamaterials
Abstract

In this talk, I will present our results on both the linear and nonlinear effects of a multilayer epsilon-near-zero metamaterial. First of all, we have used the ENZ feature of HMM as a substrate to manipulate the resonance of plasmonic nanoantennas. The localized surface plasmon resonance of metal nanoantenna is significantly influenced by the size, shape, and environment but also its substrate. 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.
