Abstract

In this work, we further explore the possibility of inducing spatial dispersion in hyperbolic metamaterials to exploit new functionalities which cannot be predicted via local approximation. For this purpose, we employed a nonlocal effective medium approximation to investigate the alteration of the topology of an iso-frequency surface of 1D hyperbolic metastructures in the presence of spatial dispersion. Over the course of our analysis, we demonstrated that strong nonlocality, enabled by a proper design of the unit cell, can substantially influence electromagnetic response of an HMM structure. We believe that our analysis demonstrated that thoughtful consideration of nonlocality in HMM structures may lead to new interesting applications.
