Simulation of the Cuticular Photonic Crystals Evolved by the Neotropic Weevil Entimus Imperialis — •Fernando Luis Rodríguez Gallegos1, Xia Wu2, and Jens Förstner1 — 1Theoretical Electrical Engineering Group, Paderborn University, Germany — 2Department of Chemistry, Paderborn University, Germany
We analyze the reflectance within the visible spectrum of the photonic crystals found in the scales of the neotropic weevil Entimus Imperialis. Our simulations show that the reflected signal at certain frequencies is cross polarized with respect to the excitation source. We present details of our simulation procedure, explain the underlying mechanism using a reduced equivalent structure and finally show the agreement to our experimental results.
