摘要

高定向散射体是用核壳微球设计的。采用遗传算法对其结构参数进行解析优化，优化方向散射，并通过时域有限差分计算对结果进行验证。利用优化后的定向散射体，偶极子的前后比和指向性分别提高到9和4.4。

Enhanced directional scattering by core-shell microspheres

Highly directional scatterers are designed using coreshell microspheres. Their structural parameters are optimized analytically by genetic algorithm to optimize directional scattering, and the results are verified by finite difference time domain calculations. Using such optimized directional scatterers, the front-to-back ratio and directivity of a dipoleis enhanced to 9 and 4.4 respectively.
