  2. 1. Phase space methods for computing creeping rays

    Author : Mohammad Motamed; Olof Runborg; Sverker Holmgren; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Creeping Rays; Phase Space Methods; High Frequency Wave Scattering Problems; Numerical analysis; Numerisk analys;

    Abstract : This thesis concerns the numerical simulation of creeping rays and their contribution to high frequency scattering problems. Creeping rays are a type of diffracted rays which are generated at the shadow line of the scatterer and propagate along geodesic paths on the scatterer surface. READ MORE

  4. 2. Topics in Analysis and Computation of Linear Wave Propagation

    Author : Mohammad Motamed; Olof Runborg; Shi Jin; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; Numerisk analys;

    Abstract : This thesis concerns the analysis and numerical simulation of wave propagation problems described by systems of linear hyperbolic partial differential equations. A major challenge in wave propagation problems is numerical simulation of high frequency waves. READ MORE
