For all three kinds of three-dimensional photonic crystal structures, their band gap width and band gap ratio can be improved with the increase of dielectric constant ratio.
对于不同的三维光子晶体结构,随着介电常数比的增大,完全禁带的宽度和带隙率也会随着增大。
The results show that the angle of incidence has effect on band-gap width and central wavelength of band gap .
理论计算和实验表明,入射角对光子带隙的宽度和带隙中心波长均有影响。
We also investigate that both increasing the width of medium plate and the radius of embedded concentric circle are in favor of the new band gap emerging.
通过改变相关参数我们发现增加介质平板的宽度,增大内嵌介质柱的半径都有利于新禁带的产生。
