Because of its incomparable advantages in light field phase control, multifunctional composite, micro-nano integration, and other aspects, metalens has great application potential in many fields. However, the design of metalens requires professional knowledge and rich experience, which makes it difficult for non-professionals to master it quickly, thus hinders the large-scale preparation of hyperlens. By means of MATLAB and finite difference time domain (FDTD) hybrid programming, the design process of dielectric metalens independent of preset physical model is studied, and the automatic design of dielectric metalens is realized. By inputting the required metalens parameters on the software interface written by MATLAB and calling FDTD design simulation program in the background to build the nanostructure, the relationship among the size of the structure, phase, and transmittance can be calculated. According to the required phase distribution, the superlens is constructed and its performance is evaluated by numerical simulation. The design process and software can greatly facilitate the design of metalens by non-specialists.

线条是艺术家用来传达信息的最常用、最直接、最有力的词汇或工具,是各种造型表现形式的灵魂。线条,是一种存在于现实生活、自然界,以及艺术家经过精神劳动生产的美术作品中的视觉形态要素。线条是美术最基本的造型手段,是构成视觉艺术形象的一种基本的形式因素,本文通过对线条进行分类,从轮廓线、结构线、留空线这三个方面来论证。
