| 摘 要： | 研究了基本结构移动、旋转、切割对左手介质传输特性的影响。用基于时域有限积分法CST软件仿真了左手介质棱镜的负折射现象和上述三种情况下的传输系数,比较了提取的标准和移动后左手介质的有效介质参数。计算结果表明,移动使左手透射峰峰值降低,通带带宽减小;若将组成左手介质的结构单元旋转,完整的左手透射峰将不再存在;不同方向的切割会不同程度地改变左手介质透射峰的性质。

| Abstract: | The effects caused by disorder,rotating and cutting in left-handed materials (LHM) are investigated. The negative refraction effect and the transmission coefficients of various shapes of LHM are simulated by CST software based on finite integration technique. The Extracted real parts of the permittivity,permeability,and index of refraction for the standard LHM are compared with those of disordered LHM. It is found that the disorder on the split ring resonators results in a lower left-handed transmission and... |
