- 27Note that the slightly larger diameter of these metallic nanodiscs leads to a larger extinction due to their specific aspect ratio and to the larger total amount of absorbent material compared to the metal-dielectric nanodisks with smaller diameters.
- 28For example, the ratio between the EM field intensity inside the Co layer of the two structures (IΦ(Au/Co/SiO2/Au)/IΦ(Au/SiO2/Co/Au)) is 0.9 for the LWP region and 0.6 for the HWP region (in agreement with the similar MO spectra observed for the two structures). The same ratio, but for the intensity of the EM field inside the three metallic layers, on the other hand, is 5 and 0.2 for the LWP and HWP, respectively, which explains the differences observed in the absorption spectra of the two structures.
