摘要
由双负介质的本构关系出发,利用时频转换关系,推导出了描述双负介质中场与流的微分方程组。讨论了双负介质和双正介质交接面处介质参数的处理方法。随后,用FDTD方法模拟了"完美"棱镜实验,与文献结果对比验证了该算法和程序的正确性。
First, from the constitutive relation and the transform relation connecting time domain and frequency domain, the differential equations of double negative material (DNM) are obtained. Second, an appropriate treatment of constitutive parameters for the interface of double negative material and double positive material is proposed Third, applying the developed algorithm we simulated the perfect lens experimentation. And in the last, numerical results comparing the paper with reference, the agreement is very well as we expect. The numerical results are given in the end.
