| 摘 要： | 本文利用传递矩阵方法研究了电磁波倾斜入射时,一维反铁磁/电介质准周期光子晶体的透射性质.反铁磁层和电介质层按Fibonacci数列排列构成准周期光子晶体.通过数值模拟发现光子禁带中有透射峰出现, 而且随着准周期光子晶体级数的增加透射峰的数目也在增加.此外,透射峰受电介质层的介电常数、入射角度和电磁波偏振影响明显.

| Abstract: | The transmission of electromagnetic wave at oblique incidence through an antiferromagnetic/nonmagnetic multilayer with a Fibonacci quasi-periodic sequence is calculated by using the transfer matrix approach. Numerical simulations show that many transmission peaks appear in the band gap. Also more and more transmission peak appear as the number of layers in the sequence increases. In addition, the dependence of transmission peak on dielectric constant of nonmagnetic layer, incident angle and wave polarization is also discussed. |
