In recent years, various kinds of optimal design approaches are intensively studied for exploring novel and higher performance microwave and optical devices beyond human knowledge. In this article, we first apply a design approach based on Bayesian optimization (BO) to design of dielectric flat lens which is expected to be used in microwave and millimeter wave region because of its excellent features, such as thin and light weight. BO is able to efficiently search optimal values of design variables compared with population based optimization, without requiring sensitivity analysis which is mandatory in the gradient method.

利用贝叶斯优化的介电平板透镜的优化设计

近年来，人们对各种最佳设计方法进行了深入研究，以探索人类所不了解的新颖，高性能的微波和光学设备。在本文中，我们首先将基于贝叶斯优化（BO）的设计方法应用于介电平板透镜的设计，该介电平板透镜由于其出色的特性（如薄，轻巧）而有望用于微波和毫米波区域。与基于总体的优化相比，BO能够有效地搜索设计变量的最佳值，而无需进行梯度方法中必需的敏感性分析。
