1. 6. Growth and Characterization of Al1-xInxN Nanospirals

   University essay from Tillämpad optik; Tekniska högskolan

   Author : Sebastian Ekeroth; [2013]
   Keywords : Nanospirals; AlInN; Sapphire; Magnetron sputtering; Sculptured thin films; Ellipsometry; Circular polarization;

   Abstract : In this work columnar nanospirals of AlInN were grown on top of TiN-coated sapphire substrates by magnetron sputtering. A variety of samples with different growth parameters were fabricated and investigated. READ MORE

3. 7. Design and Characterization of Dual Polarized feed for Satellite Communication Antenna

   University essay from Fysik och elektroteknik; Tekniska högskolan

   Author : Fayyaz Bashir; [2012]
   Keywords : ;

   Abstract : So far, extensive research has been made, and researchers have shown that use of septum polarizer for feed designing not only provides the dual polarization but also improve the input reflection and cross-polar isolation performance of the feed. In this thesis design of the feed for satellite communication antenna has been investigated, which provides the transmission in right hand circular polarization and reception in left hand circular polarization.

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

   University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolan

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

   Abstract : Light reflected from the scarab beetles Cetonia aurata (C. aurata) and Chrysina gloriosa (C. gloriosa) has left-handed polarization. READ MORE

5. 9. Spectropolarimetry of Magnetic Stars

   University essay from Observationell astrofysik

   Author : Lisa Rosén; [2011]
   Keywords : ;

   Abstract : A star´s magnetic field is important although stellar magnetic field generation is not completely understood. It´s necessary to investigate different types of stars and stars of different ages to learn how the magnetic fields are generated and how they affect the star and its surroundings. READ MORE

6. 10. An Investigation of the Polarization States of Light Reflected from Scarab Beetles of the Chrysina Genus

   University essay from Tillämpad optik

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

   Abstract : 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. READ MORE
