在800～1100nm范围内实现基于狄拉克半金属的多波段超材料波导
Realization of a multiband metamaterial waveguide based on dirac semimetal in the 800～1100nm range
摘要
Abstract
In this paper,a metamaterial waveguide with four square hole resonators based on Dirac semimetal lay-ers is proposed in the 800～1100nm range. Four transmission peaks(70％,61％,72％,and 63％)are achieved at resonance wavelengths 842nm,921nm,1010nm,and 1061nm,respectively. These transmission peaks are origi-nated from the interference effect of magnetic fields distributed in the main cavity and cavities 1,2,3,or 4. These transmission peaks can be enhanced and moved to shorter wavelengths through increasing the Fermi ener-gy. The proposed metamaterial waveguide can be applied in nanoscale filter,switch,or refractive index sensor.关键词
