Multihyperuniform Particle Composites Inspired by Avian Photoreceptor Patterns for Multifunctional Optical Applications

ABSTRACT Hyperuniform materials, characterized by anomalously suppressed long‐wavelength density fluctuations, exhibit unique optical and photonic properties distinct from both crystalline and random media. While most prior studies have focused on single‐species systems, we investigate the broader class of multihyperuniform systems inspired by biological photoreceptor mosaics. Using particle‐based models with varying species number, size ratios, and interaction competition, we demonstrate that multispecies mixtures can achieve robust and stealthy hyperuniform configurations, even in highly disordered states. We further show how these configurations can be mapped to multifunctional composites with tailored optical responses, including isotropic structural coloration, enhanced absorption, and engineered dielectric properties that facilitate transmission while suppressing scattering. In particular, we derive rigorous conditions on the cross‐structure factors quantifying inter‐species correlations, through which the multifunctional optical responses of the multihyperuniform composite can be systematically tuned. Our results highlight multihyperuniformity as a generalizable design principle for multifunctional disordered photonic materials, opening avenues for robust, tunable, and scalable optical applications.
