Negative refraction in all-dielectric metamaterial

This project focuses on the use of all dielectric resonators to achieve metamaterial negative refraction. Most of the previous literatures and methods discussed in them are based on metals, however, such designs can cause strong wear and tear on the performance of devices. In this paper, Mathematica...
