Advances in Time-Domain Modeling of Periodic Structures for Metamaterial Applications
نویسنده
چکیده
The recent interest in negative refractive-index (NRI) metamaterials stems from Veselago’s early work predicting media that simultaneously exhibit negative permittivity and negative permeability. Metamaterial structures, such as split-ring resonator and stripwires and planar-loaded transmission line grids, are artificial dielectrics, made of periodically arranged inclusions. Thus, the design of NRI metamaterials is closely associated with the formulation of periodic structure modeling techniques.

Finite-Difference Time-Domain Simulation of Light Propagation in 2D Periodic and Quasi-Periodic Photonic Structures
Ultra-short pulse is a promising technology for achieving ultra-high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. Therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide has received a great deal of attention in the recent years. We...
متن کاملA Systematic Approach to Photonic Crystal Based Metamaterial Design
Photonic crystal design procedure for negative refraction has so far been based on trial and error. In this paper, for the first time, a novel and systematic design procedure based on physical and mathematical properties of photonic crystals is proposed to design crystal equi-frequency contours (EFCs) to produce negative refraction. The EFC design is performed by the help of rectangular stair-c...
متن کاملEfficient Finite-Difference Time-Domain Modeling of Periodic Structures under Non-Periodic Sources
The paper proposes an efficient method to analyze the response of periodic structures to non-periodic excitations in the time domain, employing the Finite-Difference Time-Domain (FDTD) method. To that end, the array-scanning method, which has been previously associated with frequency-domain, integral formulations of periodic structure problems, is translated into the context of FDTD. Hence, the...
