Why does my Wavelenght Reflectiongraph not show the expectef correct wavelenghts?

Please login with a confirmed email address before reporting spam

Currently, I am constructing a nanostructure of the butterfly (Morpho Didus) to demonstrate that the butterfly's blue color is solely a result of structural reflection of light. To achieve this, I have constructed the nanostructure, formed periodic boundaries and PMS (presumably a simulation technique), and specified a port as well as the surrounding material (air). My goal is to simulate simple light rays on the nanostructure and ultimately plot a reflection graph, illustrating that the wavelengths of the blue color are predominantly reflected.

I aim to achieve a reflection graph similar to Figure 2 in the following paper, which served as the basis for my simulation:see picture below. I am striving for a reflection graph akin to the electric field in Figure 2 or as shown here: see picture below.

Unfortunately, my current reflection graphs do not make much sense. Can anyone pinpoint where exactly my problem lies? Below, you can find my file, and I am working in Study 3. Thank you very much!
