论文摘要
我们开发了一种多重散射理论,可以吸收无序培养基中的波浪。基于平均吸收能力的一般表达,我们讨论了通过使用疾病的结构相关性作为一定程度的自由度来最大化吸收的可能性。在透明背景下由吸收散射器制成的模型系统中,我们表明散射器的隐形超均匀分布使平均吸收功率达到其最大值。这项研究提供了一个理论框架,用于设计由稀释无序材料制成的有效的非共鸣吸收器,用于宽带和全向光以及其他类型的波浪。
We develop a multiple scattering theory for the absorption of waves in disordered media. Based on a general expression of the average absorbed power, we discuss the possibility to maximize absorption by using structural correlations of disorder as a degree of freedom. In a model system made of absorbing scatterers in a transparent background, we show that a stealth hyperuniform distribution of the scatterers allows the average absorbed power to reach its maximum value. This study provides a theoretical framework for the design of efficient non-resonant absorbers made of dilute disordered materials, for broadband and omnidirectional light, and other kinds of waves.
