Figure 3

Calculation results of the Transfer-Matrix (TM) method for the absorption spectra converted from the transmission spectra on quartz (a) and the absorption spectra converted from the reflection spectra on gold (b) and silver (c) of thin films with the effective medium approximation model. The thickness varied from 9 nm (equivalent to 1 layer) to 180 nm (equivalent to 20 layers).
