摘要

在本研究中,我们结合MATLAB和严格的电磁场仿真软件Computer simulation Technology,对高效宽带太赫兹超表面器件的反设计进行了联合仿真方法。在该设计方法中,嵌入遗传算法,实现自动逆设计。针对高效、宽带太赫兹元表面器件的不同要求,设置不同的目标函数,优化不同类型太赫兹元表面器件的设计。与基于接触网电场理论的理论模型相比,该设计方法基于严格的电磁仿真和遗传算法,可实现高可靠性的自动反设计。该研究为设计和优化所需的超表面器件提供了重要的指导作用和有效的方法,具有实际应用价值。

Accurate inverse design for high-efficiency and broadband terahertz devices by co-simulation with genetic algorithms
In this study, we combined MATLAB with the rigorous electromagnetic field simulation software Computer Simulation Technology to perform a co-simulation method for inverse design of high-efficiency and broadband THz metasurface devices. In the proposed design method, genetic algorithm (GA) is embedded to realize automatic and inverse design. Aiming toward the different requirements of high-efficiency and broadband THz metasurface devices, different objective functions are set to optimize the design of different types of THz metasurface devices. Based on the rigorous electromagnetic simulation and genetic algorithm, the proposed design method can realize automatic and inverse design with high reliability, compared to the theoretical model based on catenary e-field theory. This study provides an important guiding role and an efficient method for designing and optimizing required metasurface devices with practical applied value.
