论文摘要
我们提出了一种使用介电纳米结构的半分析建模在光学设计中集成跨额定面积的新方法。后者计算出元图上的电场的输出阶段，从而使其与射线追踪软件一起使用。该工具提供了一种在光学系统中使用元信息的方法，同时使用内置优化过程来避免耗时计算。为了证明我们方法的适用性和多功能性，我们提出了由折射元素和元表面组成的三重态的变化。对于每个系统，都可以实现类似的光学性能。我们独特而创新的方法来加入元信息和射线追踪，有可能通过利用元信息的丰富性和传统镜头设计软件的功能来促进创新系统的设计。
We propose a new method for integrating metasurfaces in optical design using semi-analytical modelling of dielectric nanostructures. The latter computes the output phase of an electric field incident on the metasurface, allowing their use with ray-tracing software. This tool provides a method to use metasurfaces in optical systems while using built-in optimization processes to avoid time-consuming computation. To demonstrate the applicability and versatility of our method, we present variations of a triplet composed of refractive elements and a metasurface. For each of the systems, similar optical performances are achieved. Our unique and innovative approach to joining metasurfaces and ray tracing has the potential to promote the design of innovative systems by exploiting the richness of metasurfaces and the functionality of conventional lens design software.
