摘　　要：应用传输矩阵法数值研究了含纳米磁流体一维Fibonacci准周期结构局域模的磁控可调特性.首先构建一维Fibonacci准周期结构磁流体光子晶体的物理模型,然后应用传输矩阵法,数值计算含纳米磁流体一维Fibonacci准周期结构的透射谱,最后讨论局域模的磁控可调特性.结果表明:局域模波长随磁流体折射率的增大向长波方向移动;随着含纳米磁流体一维Fibonacci准周期结构的代数的增加,其局域模的个数也随着增加,且局域模的品质因子也增大.The magnetic control adjustable characteristics of one-dimensional Fibonacci quasiperiodic structure containing nanoparticle magnetic fluid localized modes is studied by using the transfer matrix method. First,building the physical model of one-dimensional Fibonacci quasiperiodic structure containing nanoparticle magnetic fluid photonic crystal. Then,the transmission spectrum of one-dimensional Fibonacci quasiperiodic structure containing nanoparticle magnetic fluid is calculated by transfer matrix method. Finally,discussing the localized modes of magnetic control adjustable features. The results show that the wavelength of the local mode shift to the long-wave direction with the refractive index of magnetic fluid increases. When the generation of one-dimensional Fibonacci quasiperiodic structure with nanoparticle magnetic fluid increased,the number of local mode increased as well,and the quality factor gets higher.
