Abstract
This article discusses the physical theory and mathematical modeling of epsilon-negative (ENG) material. Numerical simulation results are also given in later part of this article, and they prove that this kind of material has a great shielding effect. We mainly focus on the modeling and simulation of one dimensional epsilon-negative (ENG) material. First we set up a Drude model to theoretically simulate ENG material, and then use the finite difference time-domain methods to analyze the electromagnetic wave propagation in our shielding material.
