Data for: Microwave nondestructive detection and quantitative evaluation of kissing defects in GFRP laminates

1. The two ZIP files named "experimental data-GFRP" and "experimental data-Teflon" are original experimental detection data for GFRP specimen and Teflon specimen.
2. Subfolders are named by the thickness of kissing defect.
3. In corresponding subfolders, CSV files are named in two forms:
(1) "thickness of kissing defect-experimental order" (Take "17.52-2.csv" as an example, it is the frequency spectrum data for 17.52 um-thick defect in the second detection.)
(2)"0-experimental order" (Take "0-2.csv" as an example, it is the frequency spectrum data for intact specimen without defect in the second detection)

1. 两个分别命名为"experimental data-GFRP"与"experimental data-Teflon"的ZIP压缩包，对应玻璃纤维增强塑料（GFRP）试样与聚四氟乙烯（Teflon）试样的原始实验检测数据。
2. 子文件夹以接吻缺陷（kissing defect）的厚度进行命名。
3. 对应子文件夹内的CSV文件采用两种命名形式：
(1) 格式为"接吻缺陷厚度-实验序号"：以"17.52-2.csv"为例，该文件对应厚度为17.52微米的缺陷试样在第2次检测时的频谱数据。
(2) 格式为"0-实验序号"：以"0-2.csv"为例，该文件对应无缺陷的完好试样在第2次检测时的频谱数据。
