Figure 5. Measured reflectance plots for sucrose-solution-infiltrated platform A.
Reflectance measured as a function of θ at 472.44 THz of platform A when an aqueous solution of sucrose infiltrates and lies atop the three-period CSTF.The incident light is p polarized. The blue solid line is for the 0 M solution, the red dashed line is for the 0.183 M solution, and the black dashed-dotted line is for the 0.367 M solution. The reflectance dips indicating the excitation of the two SPP-wave modes are identified by ‘1' and ‘2'.
