We investigate the influence of metamaterials on the scaling laws of the transmission on multilayered structures composed of random sequences of ordinary dielectric and metamaterial layers. The spectrally averaged transmission in a frequency range around the fully transparent resonant mode is shown to decay with the total number of layers as 1/N. Such thickness dependence is faster than the 1/N(1/2) decay recently reported to take place in random sequences of ordinary dielectric slabs. The interplay of strong localization and the emergence of resonant modes within the gap leads to a non-monotonous disorder dependence of the transmission that reaches a minimum at an intermediate disorder strength.
我们研究了超材料对由普通电介质和超材料层的随机序列组成的多层结构中传输的标度律的影响。结果表明，在完全透明共振模式附近的频率范围内，光谱平均传输随层数总数以1/N的形式衰减。这种厚度依赖性比最近报道的普通电介质平板随机序列中发生的1/N(1/2)衰减更快。强局域化与能隙内共振模式的出现之间的相互作用导致传输的无序依赖性非单调，在中等无序强度下达到最小值。
