摘　　要：文章设计了一种新型六边形晶格光子晶体,它在可见光区域具有负折射特性。进一步改变这种光子晶体的参数,可以得到渐变折射率光子晶体,其聚焦性能得到明显改善,可以用于聚焦平面波。文章通过数值计算验证了这种光子晶体的负折射特性和聚焦效果。A new type of hexagonal lattice photonic crystal is designed,which has negative refraction characteristics in the visible light region.By further changing the parameters of this kind of photonic crystal,we can obtain a graded index photonic crystal,whose focusing performance has been signif icantly improved,which can be used to focus plane waves.The negative refraction characteristics and focusing effect of the photonic crystal are verif ied by numerical calculation.
