频率编码超构材料测试数据

本数据集为频率编码现场可编程超表面样品在4组编码下、各谐波频点的实测方向图数据。数据集包含4个后缀为.dat的数据文件，分别对应以下四种目标编码对应的方向图数据：
1. +1阶/-1阶谐波频率的波束指向为+30度/-20度；
2. +1阶/-1阶谐波频率的波束指向为+35度/-35度；
3. +1阶/-1阶谐波频率的波束指向为+40度/-40度；
4. +3阶/-2阶谐波频率的波束指向为+40度/-30度。
每个数据文件中记录有实测数据的频点、方位角和对应的S12参数大小（dB值）。

This dataset contains measured radiation pattern data at each harmonic frequency for frequency-coded field-programmable metasurface samples under four coding configurations. The dataset includes 4 data files with the .dat suffix, which correspond to the radiation pattern data of the following four target coding schemes respectively:
1. The beam directions at +1st/-1st harmonic frequencies are +30° and -20° respectively;
2. The beam directions at +1st/-1st harmonic frequencies are +35° and -35° respectively;
3. The beam directions at +1st/-1st harmonic frequencies are +40° and -40° respectively;
4. The beam directions at +3rd/-2nd harmonic frequencies are +40° and -30° respectively.
Each data file records the measured frequency points, azimuth angles, and corresponding S12 parameter values (in dB).
