   Keywords : Optical Studies; Micro-Structure Modeling; Circular-Polarizing; Cetonia aurata; Potosia cuprea; Liocola marmorata; Scarab beetles; RC2; Ellipsometry; Guldbaggar;

   Abstract : The aim of the work presented in this thesis is to contribute to a fundamental understanding of polarizing phenomena in some scarab beetles. The aim is also to study the beetle structures as inspiration in fabrication of artificially sculptured films. READ MORE

4. 3. Optical Studies ofNano-Structures in the BeetleCetonia Aurata

   University essay from Institutionen för fysik, kemi och biologi

   Author : Rizwana Shamim; [2009]
   Keywords : Cetonia aurata; Mueller-matrix ellipsometry; Helicoidal structures; Left-handed circularly polarized light;

   Abstract :       The main objective of this thesis is to study the polarization effects of the beetle Cetonia aurata using Mueller-matrix ellipsometry. The outer shell of the beetle consists of complex microstructures which control the polarization of the reflected light. It has metallic appearance which originates from helicoidal structures.
