A nonperturbative and universal FDTD model is proposed to investigate the nonlinear responses from metallic metamaterials. By coupling the hydrodynamic equation to the Maxwell equation, the multiphysics model enables to investigate both linear and nonlinear dynamics of free electron gas within the metallic metamaterials without any approximations and prior assumptions. Moreover, the proposed FDFD...
The finite-difference time-domain (FDTD) method is proposed to model Maxwell-Bloch equations with a four-level quantum system for investigating the nano-structures incorporated with gain materials. To understand the lasing behavior and loss compensation mechanism of the gain material, a self-consistent computational scheme is presented. Comparisons between optical and homogeneous Pumping are given...
In this paper, we focused on the study of electromagnetic (EM) wave propagation in a particular anisotropic medium—Infinity-anisotropic (IA) metamaterial. IA metamaterials, which include infinity index-anisotropic and infinity loss-anisotropic metamaterial, have the ability to suppress the diffraction limit of EM wave. Thus the deep subwavelength wave could propagate in the IA metamaterials without...
Metamaterials have attracted much attention in recent years because of their electromagnetic exquisite proprieties. For this we will introduce in this paper the modeling of a whole structure in metamaterials by equivalent circuit model. We begin by modeling the SRR (Split Ring Resonator), then we model the HIS (High Impedance Surfaces). In order to validate models, we compare the results obtained...
