Abstract

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.

摘要

我们展示了在具有高介电常数的超均匀无序圆柱阵列中的波传输实验。利用微波,我们表明,根据电磁波的频率ν,同一材料可以表现出透明性、光子扩散、安德森局域化或完全带隙。有趣的是,我们发现了第二个较弱的带隙,它似乎与结构因子的第二个峰值有关。我们的结果强调了不同长度尺度上的空间相关性对光子带隙形成的重要性。
