Abstract. The magnetic control tunable characteristics of localized modes of One-dimensional Cantor quasicrystal structure containing nanoparticle magnetic fluid is studied by using the transfer matrix method. First, the physical model of One-dimensional Cantor quasicrystal structure containing nanoparticle magnetic fluid is built. Then, the transmission spectrum of One-dimensional Cantor quasicrystals structure containing nanoparticle magnetic fluid is calculated by transfer matrix method. Finally, the magnetic control tunable characteristics of localized modes are discussed. The results show that the generation of One-dimensional Cantor quasicrystal structure containing nanoparticle magnetic fluid increased, the number of localized modes increased as well; the wavelength of localized modes shift to the long-wave direction with the refractive index of magnetic fluid increasing; the higher generation, the higher of the quality factor of the split localized modes; the wavelength drift variation decreases with the increasing of localized modes level at the same generation.
