摘要
模拟一个12GHz谐振频率下具有负介电常数和磁导率的新型C型单元电池,通常称为双负超材料(DNG)或左手材料.DNG形状为在电介质的一侧有相反的C谐振器,而在另一侧也是相同的形状.使用微波工作室(MWS)中的计算机模拟技术(CST)从DNG结构的模拟仿真中确定散射参数以及介电常数,渗透率和折射率.为了验证结构参数的负值,使用了MATLAB.由于其简单性,可扩展性和双负极材料的特性,这是一种在电磁学领域的新颖且有前途的设计方法.
The layout of this research work is to simulate a novel opposite C-shape unit cell at resonance frequency of 1 2 GHz,having negative permittivity and permeability,which is often,referred to as double negative metamaterial(DNG)or left-handed material.The DNG shape includes opposite C resonators on one side of dielectric medium and same shape on other side.The Scattering parameters as well as permittivity,permeability and refractive index are determined from the simulated Simulations of DNG structure using Computer simulation technology(CST)in microwave studio(MWS).For verification of negative values of structure’s parameter,MATLAB was used.This is a novel and promising design approach in the world of electromagnetics due to its simplicity,scalability and characteristics of double-negative material.
