摘要

计算研究了在MgAl2O4尖晶石陶瓷窗上制备的两层母眼纳米结构。我们研究了结构参数，包括高度、宽度和形状，以优化其在宽带宽上的功率传输效率。我们发现了一种双层母眼结构，其上部结构的锥呈凹形，在0.4 μm ~ 5.0 μm波长范围内，理论上可以达到99.8%以上的正入射透射率。

Optimized two-layer motheye structures for MgAl2O4 spinel ceramic windows

We computationally study two-layer motheye nanostructures fabricated on MgAl2O4 spinel ceramic windows. We investigated the parameters of the structure, including height, width, and shape, in order to optimize its power transmission efficiency over a broad bandwidth. We found a two-layer motheye structure in which the cones of the upper structure have a concave shape that can theoretically achieve more than 99.8% transmission at normal incidence in the wavelength range between 0.4 μm and 5.0 μm.
