超表面频率色散和角度色散的基础理论和方法数据集

本数据集基于电磁仿真软件，记录了在调控超表面频率和角度色散研究过程产生的数据。通过COMSOL Multiphysics, CST STUDIO SUITE和AnsysLumericalFDTD等电磁仿真软件，计算了不同入射光频率下和不同入射角度下超表面的电磁响应，从而对调控超表面频率和角度色散性质的基础理论和实现方法进行探究，并针对多层级联架构拓宽超表面聚光器频段和角度响应范围设计进行仿真模拟，获得不同波长和不同入射角度下的电场分布数据。通过Matlab将数据绘制成图分别得到不同波长和不同入射角度下的聚光电场分布图，Matlab和Origin软件进行数据处理分别得到焦距、效率随着波长、入射角度变化的数据。利用网络分析仪、三维精密平移台和高频探针在实验上实现了对超表面角度色散性质的调控。在FDTD中仿真时间设定为1000fs以保证场有足够的衰减；空间范围限定于小尺寸结构样品仿真。数据质量通过网格划分策略和仿真时长与自动截断阈值设置等控制，通过仿真收敛条件等评估。数据量1.34GBThis dataset is constructed based on electromagnetic simulation software, and records the data generated during the study of regulating the frequency and angular dispersion of metasurfaces. Using electromagnetic simulation tools including COMSOL Multiphysics, CST STUDIO SUITE, and Ansys Lumerical FDTD, we calculated the electromagnetic responses of metasurfaces under different incident optical frequencies and incident angles, explored the fundamental theories and implementation approaches for regulating the frequency and angular dispersion properties of metasurfaces, and conducted simulation studies on the design of multi-level cascaded architectures aimed at broadening the frequency band and angular response range of metasurface concentrators, thereby acquiring electric field distribution data under different wavelengths and incident angles. We utilized Matlab to plot the data and obtained focusing electric field distribution maps corresponding to different wavelengths and incident angles respectively; additionally, we performed data processing with Matlab and Origin software to derive the datasets of focal length and collection efficiency varying with wavelength and incident angle. We experimentally realized the regulation of the angular dispersion properties of metasurfaces by employing a network analyzer, three-dimensional precision translation stage, and high-frequency probe. In FDTD simulations, the simulation duration was set to 1000 fs to ensure sufficient field decay, while the spatial scope was limited to simulations of small-sized structural samples. The data quality was controlled via strategies such as meshing schemes, simulation duration, and automatic truncation threshold settings, and evaluated based on indicators like simulation convergence criteria. The total size of this dataset is 1.34 GB.
