  1. 1. An Investigation of the Polarizing Properties and Structural Characteristics in theCuticles of the Scarab Beetles Chrysina gloriosa and Cetonia aurata

    Master-uppsats, Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Författare :Lía Fernández del Río; [2012]
    Nyckelord :Near-circular polarization; Large ellipticity; Mueller matrix; Spectroscopic ellipsometry; Scarab beetle; Scanning electron microscopy; modelling.;

    Sammanfattning : Light reflected from the scarab beetles Cetonia aurata (C. aurata) and Chrysina gloriosa (C. gloriosa) has left-handed polarization. LÄS MER

  3. 2. An Investigation of the Polarization States of Light Reflected from Scarab Beetles of the Chrysina Genus

    Kandidat-uppsats, Tillämpad optik

    Författare :Lia Fernandez del Rio; [2011]
    Nyckelord :Near-circular polarization; Large ellipticity; Mueller matrix; Spectroscopic ellipsometry; Scarab beetle; Chrysina genus;

    Sammanfattning : The polarization behaviour for six species of Scarab beetles from the Chrysina genus is investigated with Mueller Matrix Spectroscopic Ellipsometer (MMSE). The m41 element of the matrix, which is related to the circular polarization behaviour, is analysed. LÄS MER

  4. 3. Identification of olfactory receptor neurons in twoSpecies of scarab beetles: a comparative study bymeans of single sensillum recording

    Master-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Hamida Khbaish; [2010]
    Nyckelord :olfaction; electrophysiology; scarab beetles; Pachnoda marginata; Pachnoda interrupta; single sensillum recording; olfactory receptor neurons;

    Sammanfattning : Few studies have addressed how olfactory systems may be adapted to different odour environments. I have performed the largest study to date, comparing olfactory receptor neurons in the two congeneric species of scarab beetle, P. marginata and P. interrupta. LÄS MER

  5. 4. Optical Studies and Micro-Structure Modeling of the Circular-Polarizing Scarab Beetles Cetonia aurata, Potosia cuprea, Liocola marmorata

    Kandidat-uppsats, Tillämpad optik

    Författare :Johan Gustafson; [2010]
    Nyckelord :Optical Studies; Micro-Structure Modeling; Circular-Polarizing; Cetonia aurata; Potosia cuprea; Liocola marmorata; Scarab beetles; RC2; Ellipsometry; Guldbaggar;

    Sammanfattning : 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. LÄS MER
