近年来,各种优化设计方法被广泛研究,以探索超越人类知识的新型和更高性能的微波和光学器件。在这篇文章中,我们首先应用基于贝叶斯优化(BO)的设计方法来设计的介质平面透镜,这是预期将用于微波和毫米波领域,因为它的优良特性,如薄,重量轻。与基于种群的优化相比,BO能够有效地搜索设计变量的最优值,而不需要梯度法中强制性的灵敏度分析。
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.
