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

    Author : Adil Baitenov; Sergei Popov; Sergey Ponomarenko; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Optical Properties of Nanoparticles in Composite Materials

    Author : Lin Dong; Sergei Popov; Ari Friberg; Toralf Scharf; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Nanoparticles are synthetic structures with dimension from 1 to 100 nanometers and are various in types. Some favorable properties peculiar to the nanoparticles (generally owing to size effects) make them prevailing and beneficial for applications in different scientific and engineering fields.
