论文摘要
我们提出了具有高介电介电常数的圆柱体过度无序阵列的波传输实验。使用微波，我们表明相同的材料可以显示透明度，光子扩散，安德森定位或完整的带隙，具体取决于电磁波的频率$ν$。有趣的是，我们发现第二个较弱的带隙，这似乎与结构因子的第二个峰有关。我们的结果强调了空间相关性在不同长度尺度上的重要性对于光子带隙的形成。
We present wave transport experiments in hyperuniform disordered arrays of cylinders with high dielectric permittivity. Using microwaves, we show that the same material can display transparency, photon diffusion, Anderson localization, or a full band gap, depending on the frequency $ν$ of the electromagnetic wave. Interestingly, we find a second weaker band gap, which appears to be related to the second peak of the structure factor. Our results emphasize the importance of spatial correlations on different length scales for the formation of photonic band gaps.
