Ateneo Photonics Laboratory publishes in Elsevier’s Materials and Engineering C 2010: Diffraction from relief gratings on a biomimetic elastomer cast

Dr. Raphael Guerrero and his undergraduate student, Erika B. Aranas, have a new paper published in Elsevier’s Materials and Engineering C:

Diffraction from relief gratings on a biomimetic elastomer cast

Abstract. Biomimetic optical elements combine the optimized designs of nature with the versatility of materials engineering. We employ a beetle carapace as the template for fabricating relief gratings on an elastomer substrate. Biological surface features are successfully replicated by a direct casting procedure. Far-field diffraction effects are discussed in terms of the Fraunhofer approximation in Fourier space.
