  2. 1. A Discrete Dipole Approximation Forward Solver for Microwave Breast Imaging

    Author : Samar Hosseinzadegan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave imaging; forward problem; breast cancer; tomography; computation time.;

    Abstract : Breast cancer has the highest incidence rate of cancers in women worldwide. Early detection results in a higher survival rate. Drawbacks in conventional imaging modalities, including painful exams, have limited periodic breast screening. READ MORE

  4. 2. Fast Microwave Tomography Algorithm for Breast Cancer Imaging

    Author : Samar Hosseinzadegan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; breast cancer; computational cost; inverse problem; discrete dipole approximation; microwave tomography; forward solver; Jacobian matrix;

    Abstract : Microwave tomography has shown promise for breast cancer imaging. The microwaves are harmless to body tissues, which makes microwave tomography a safe adjuvant screening to mammography. READ MORE

  5. 3. Theoretical Studies of Simple Polar Fluids

    Author : Joakim Stenhammar; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polar fluids; Dielectric theory; van der Waals forces; Molecular simulation;

    Abstract : Fluids composed of dipolar molecules are ubiquitous in nature, with water being the most prominent example. Due to their great importance and large complexity, a basic scientific understanding of the structure and thermodynamics of polar fluids is essential. READ MORE

  6. 4. Modelling optical properties of morphologically complex soot aerosols

    Author : Franz Kanngiesser; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aerosol; remote sensing; depolarisation; lidar; black carbon; scattering;

    Abstract : Soot containing aerosol has both adverse impacts on the Earth's climate and on human health. Monitoring soot sources, transport pathways and sinks on global scale requires satellite-borne remote sensing techniques. READ MORE

  7. 5. Numerical Simulations of Plasmonic Nanostructures

    Author : Joan Alegret; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoholes; DDA; Green s tensor; nanostructures; surface plasmons;

    Abstract : This thesis focuses on the study of metallic nanostructures that support plasmons. Special emphasis is devoted to two specific numerical methods that allow us to predict plasmon characteristics: the discrete dipole approximation (DDA) and the Green's tensor (GT) method. READ MORE
