The data of the article "Carbon Dioxide Sensor Based on Gas-Tuned Propagation Length in Hybrid Composite Silver-Layer Structures"

This dataset mainly consists of the following 8 files: t1 is the thickness of the silver layer, t2 is the thickness of the dielectric layer, the tangential mode magnetic field Hy, the single-layer file contains the single-layer Hy file, the single-layer mode 1 and mode 2 propagation length (t1=100nm, 0ppm) file is the data calculated by COMSOL and MATLAB under t1=100nm, 0ppm conditions, that is, the data in Figure 2, the single-layer propagation length change and change rate file is the data for studying the single-layer propagation length change and change rate under different t1 conditions, that is, the data in Figure 3, and the single-layer mode 1 propagation length (t1=50~150nm) file is the data exported by COMSOL for calculating Figure 3; The double-layer file contains double-layer Hy files.

The double-layer mode 1 and 2 propagation length (t1=t2=100nm, 0ppm) files are data calculated by COMSOL and MATLAB under t1=t2=100nm, 0ppm conditions, as shown in Figure 4. The double-layer propagation length change and rate of change (different t2, wavelength) files are data for studying the change and rate of change of different dielectric layer thicknesses and wavelengths in the double-layer structure, as shown in Figure 5.

The double-layer propagation length change and rate of change (different t1, wavelength) files are data for studying the change and rate of change of different silver layer thicknesses and wavelengths in the double-layer structure, as shown in Figure 6. The double-layer mode 1 propagation length (t2=100nm) file is Calculate the data exported from COMSOL in Figure 6; The three-layer file contains three Hy files, namely the data in Figure 7.

The three-layer propagation length change and change rate files are used to study the change and change rate of different silver layer thicknesses and wavelengths in the three-layer structure, namely the data in Figure 8. The three-layer propagation length file is used to calculate the data exported from COMSOL in Figure 8; The PHMB file contains data on the refractive index of PHMB at different concentrations of carbon dioxide, as shown in Figure 1 (b); The files of different layer change rates and changes are data used to study the impact of different layers on them, as shown in Figure 9.

The multilayered1 and multilayered2 files are MATLAB codes for calculating propagation length in single and double layers, which need to be opened in MATLAB; The Ag file is the n and k function data of silver when calculating propagation length.
