Automatic Design Technology and Software of Dielectric Metalens
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.
