Analysis of biological creature color appearance via FDTD simulation

In this research, the finite-difference time-domain (FDTD) simulation technique is employed to analyze the optical characteristics of the following creatures: Morpho menelaus, Euprymna scolopes, Dynastes hercules, Hoplia coerulea, and Paracheirodon innesi. The layered geometries are simulated to decipher the effect on color appearances, including: thickness of the periodic layered structure, spacing between layers and the number of layers. Furthermore, we compare the biological structures of various creatures; research findings suggest that the color appearances may be accounted for by the specific geometrical nanostructure.
