  2. 1. Numerical approximations of time domain boundary integral equation for wave propagation

    Author : Andreas Atle; KTH; []
    Keywords : MOT; Marching on in time; boundary integral equations;

    Abstract : Boundary integral equation techniques are useful in thenumerical simulation of scattering problems for wave equations.Their advantage over methods based on partial di.erentialequations comes from the lack of phase errors in the wavepropagation and from the fact that only the boundary of thescattering object needs to be discretized.

  4. 2. Approximations of Integral Equations for WaveScattering

    Author : Andreas Atle; Björn Engquist; Richard Tsai; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Integral equations; Marching on in time; On surface radiation condition; Physical Optics; Numerical analysis; Numerisk analys;

    Abstract : Wave scattering is the phenomenon in which a wave field interacts with physical objects. An incoming wave is scattered at the surface of the object and a scattered wave is produced. Common practical cases are acoustic, electromagnetic and elastic wave scattering. READ MORE
