研究目的
To develop a model system that mimics the optical properties of white beetles' scales, explaining their high scattering strength within a thin layer of low refractive index material.
研究成果
The model based on constructive interference and multiple light scattering between detuned Bragg stacks explains the optical properties of the beetles' scales in the visible spectral range. It demonstrates that the scales' structure can be derived from a strictly ordered structure by introducing disorder, offering insights into disordered structures in general and potential applications in white coloration.
研究不足
The model does not fully replicate the beetles' scales' behavior in the near infrared range without additional modifications. The absence of struts oriented in the propagation direction of light in the model may account for differences in reflectivity for larger wavelengths.
