SUMMARY:Computational Mathematics Seminar - Graham Mauer
DESCRIPTION:Graham Mauer\, Department of Applied Mathematics\, University o
 f Colorado Boulder A Direct FEM-BIE Coupling for Free-Space Helmholtz Scat
 tering Free space scattering problems involving locally compact\, non-homo
 geneous media arise in a variety of applications including medical imaging
 \, seismology\, and acoustics. These problems are challenging because it i
 s impossible to discretize all of space. Conventional solution methods\, s
 uch as absorbing boundary conditions and perfectly matched layers\, trunca
 te the domain but sometimes give rise to artificial reflections especially
  as the frequency grows. We propose a finite element (FEM) -based techniqu
 e that utilizes integral equations to naturally satisfy the radiation cond
 ition and mitigate such reflections. The technique is a modernized FEM-BEM
  coupling scheme. An artificial boundary is introduced that contains the s
 upport of the variable media. In that region\, a FEM is employed and a Dir
 ichlet-to-Neumann operator is constructed. This…\n\nhttps://localz.event
