Results of infrared spectroscopic analysis

Caption

<b>(Left)</b> The graphs show the measured reflection spectra of the metamaterial absorber developed by KIMM and UNIST. From top to bottom, the vertical nanogaps are 30, 15, and 10 nm. The black line represents the reflection spectra of the metamaterial absorber before ODT coating, and the red line shows the reflection spectra after ODT coating. The amount of sinking of the two lines is the amount of light gathered (= energy absorbed = lower reflection). The red line representing reflectance after ODT coating rises when the wavelength is between 3.4 and 3.5, indicating signal amplification. If no signals were detected, the graph should be the same as that of the blue line. The difference between the two values is approximately 36%. <br><b> (Right)</b> Detected signal spectra of the metamaterial absorber developed by KIMM and UNIST.
