在本工作中，我们从理论上研究了含有纳米复合材料缺陷层的一维光子晶体在红外辐射中的传输特性。根据特征矩阵法的基本原理，得到了理论上的处理。在这里，由超导材料的纳米颗粒设计的纳米复合材料被排列成介电介质。数值结果阐明了体积分数和工作温度对纳米复合材料有效介电常数的影响。因此，体积分数、工作温度以及介质材料的介电常数和阈值频率等参数都会对缺陷模的特性产生显著的影响。因此，我们的结构在窄带滤光器和光电子应用中可能是非常有前途的。
In the present work, we investigate theoretically the transmission characteristics of one-dimensional photonic crystals that contain a defect layer of a nanocomposite material in infrared radiation. The theoretical treatment is obtained depending on the fundamentals of the characteristic matrix method. Here, the nanocomposite designed from nanoparticles of a superconducting material is arranged into a dielectric medium. The numerical results clarify the acute effect of the volume fraction and the operating temperature on the effective permittivity of the nanocomposite material. Therefore, the volume fraction, the operating temperature and other parameters such as the permittivity of the dielectric material and the threshold frequency could have a significant effect on the characteristics of the defect modes. Thus, our structure may be very promising in many applications such as narrow band filters and among optoelectronic applications.
