Near-infrared embedded metamaterial composed of circular ring resonator with wire strip topology for free-space applications

摘要

A Near-Infrared (NIR) embedded metamaterial (MTM) structure is proposed in this study. The computational design process of the complex material and the results of that process are covered and discussed. According to the simulations, periodically engineered silver resonators that are combined with SiO2 give good transmission characteristics at NIR frequency range when their lattice and resonator parameters are well adjusted. Besides, the simulation results are in somehow agreement with the mathematical formulations of the predicted polarization fields in terms of the resonator parameters. The entire combination provides an opportunity to control the wave propagation for the benefit of optical communication applications.
