基于空气孔的光子晶体亚波长成像的特性研究*

摘要

负折射率材料因为其奇异的特性成为广泛研究的对象，尤其是光子晶体平板的完美成像。本文采用空气孔在硅介质中周期性排列构成六角结构的光子晶体结构，用平面波展开法及FDTD方法，研究了该光子晶体的亚波长成像能力还研究了入射波长以及温度漂移对该光子晶体平面亚波长成像的影响。%Negative refractivity has been extensively studied, especially in the perfect imaging photonic crystal slab, for its fantastic characteristics. The photonic crystals sub-wavelength imaging is investigated by finite-difference time-domain (FDTD) simulation and numerical analysis. Impact of wavelength and temperature drift on the sub-wavelength imaging of photonic crystal with negative refraction has been studied in this paper.
