| 摘 要： | 电磁波在经过负折射率材料以后,偏振状态会有所改变.对开口谐振环电磁响应特性了解的基础上,采用时域有限积分方法,分别研究了方形、六边形和圆形开口谐振环负折射率材料在不同频率处以及斜入射时对电磁波偏振特性的影响.仿真结果表明,不同的结构、频率和入射角度,电磁波偏振翻转的程度有所不同.研究结果可为电磁波偏振状态的调控提供一定的理论依据和借鉴.

| Abstract: | Reflected from the negative refractive index material, polarization state of electromagnetic wave will change. The electromagnetic response characteristics of the opening resonance loop structure as a basic principle, which was used by method of the finite integral time domain, square, round, hexagonal openings resonant ring were researched the influence on the polarization characteristics of electromagnetic waves in different frequencies and oblique incidence, respectively. The simulation results were shown that the polarization conversion of electromagnetic wave was not same with the different structure,the frequency and the incident angle. The results of this paper can provide some theoretical basis and reference for the control of the electromagnetic wave of polarization state. |
