  2. 1. Optical characterization of wide band gap materials by spectroscopic ellipsometry

    Author : O. P. Alexander Lindquist; Linköpings universitet; []
    Keywords : Wide Band Gap materials; ellipsometry; SiC; GaN;

    Abstract : Spectroscopic ellipsometry has been employed in the study of wide band gap materials. Ellipsometry is based on the study of changes in the polarization state of light upon reflection on a surface. READ MORE

  4. 2. Estimation of Forest Biomass and Faraday Rotation Using Polarimetric L-/P-band SAR

    Author : Gustaf Sandberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; linear regression; Remote sensing; forest biomass retrieval; P-band; synthetic aperture radar SAR ; calibration; L-band;

    Abstract : At present the greatest source of uncertainty in the global carbon cycle is in the terrestrialecosystems. In order to reduce these uncertainties it is necessary to provide consistent andaccurate global estimates of the biomass contained in the forests of the world. READ MORE

  5. 3. Ellipsometric studies of SiC in the infrared, visual and ultraviolet spectral region

    Author : O. P. Alexander Lindquist; Stergios Logothetidis; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Spectroscopic ellipsometry has been used to determine the dielectric function of the most common polytypes, 3C, 4H and 6H, of SiC and also of some related materials. Measurements have been performed in the infrared, visible and ultraviolet energy region. READ MORE

  6. 4. Biomass Retrieval in Topographic Boreal Forest using Polarimetric and Tomographic SAR in P- and L-band

    Author : Erik Blomberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forest Biomass; Tomography; SAR; L-band; EM Modelling; P-Band;

    Abstract : Forests and their associated habitats are an integral part of Earth's biosphere and provide essential environmental services. There is an ever present need for accurate and economic monitoring of forest parameters such as biomass - of great interest both locally, for forest management and resource utilization, and globally as it represents stored atmospheric CO2 and one of the largest uncertainties in climate modelling.

  7. 5. The choreography of protein vibrations : Improved methods of observing and simulating the infrared absorption of proteins

    Author : Eeva-Liisa Karjalainen; Andreas Barth; Astrid Gräslund; Timothy A. Keiderling; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Infrared spectroscopy; FTIR; protein; atpase; amyloid; caged compound; amide I; transition dipole coupling; exciton theory; simulation; Molecular biophysics; Molekylär biofysik; Biophysics; biofysik;

    Abstract : The work presented in this thesis has striven toward improving the capability to study proteins using infrared (IR) spectroscopy. This includes development of new and improved experimental and theoretical methods to selectively observe and simulate protein vibrations. READ MORE
