  1. 1. Light propagation in an anisotropically scattering medium

    Författare :Elena Vasileva; Sergei Popov; Miguel A. Alonso; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; anisotropic light scattering; scattering material characterization; polarization dependent scattering; diffusive media; hierarchical structure; biocomposites; wood modification; transparent wood; microfibrils angle; organic materials; polymer active devices; dye lasers; coherence; polarization; degree of polarization.; Fysik; Physics;

    Sammanfattning : Scattering is the main phenomenon of light-matter interaction. In this thesis, we consider one specific case of light propagation in a material whose structure causes anisotropic optical scattering - transparent wood. LÄS MER

  3. 2. Light propagation and photonic functionalization of semi-ordered material (transparent wood)

    Författare :Adil Baitenov; Sergei Popov; Sergey Ponomarenko; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; light scattering; scattering material; hierarchical structure; FEM model; wood modification; random lasers; dye lasers; transparent wood; adsorption; diffusive media; Optics and Photonics; Optik och fotonik;

    Sammanfattning : Investigating novel materials requires understanding their chemical and optical properties, which allows for finding their uses through functionalization by chemical modification. In this thesis, we are focusing on a material with high anisotropic scattering - transparent wood. LÄS MER

  5. 4. Studies in Physiological Optics and Microwave Hyperthermia

    Författare :Claes M. E. Beckman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optics; cancer treatment; light scattering;

    Sammanfattning : This thesis deals with the optics of the eye, the sky and microwave induced hyperthermia treatment of cancer. Light scattering in normal eyes is reviewed and its influence on vision is discussed in some detail. LÄS MER

  7. 5. The Role of Molecular Heterogeneity in the Structural Dynamics of Aqueous Solutions

    Författare :Sharon Berkowicz; Fivos Perakis; Giulio Monaco; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Water; Aqueous solutions; X-ray scattering; X-ray photon correlation spectroscopy; Dynamic light scattering; kemisk fysik; Chemical Physics;

    Sammanfattning : The liquid-liquid critical point hypothesis suggests that liquid water exists in two liquid states with different local structures, so-called high- and low-density liquid (HDL, LDL). At ambient pressure water locally fluctuates between these two states, with the fluctuations becoming more pronounced as the liquid is supercooled. LÄS MER
