The Half-space Matching Method for Solving Scattering in Complex Media

Explore the Half-space Matching Method for solving scattering problems in complex media in this virtual seminar talk from the Sixth Imaging & Inverse Problems (IMAGINE) OneWorld SIAM-IS series. Delve into the research presented by Sonia Fliss from Ensta Paris, which focuses on time-harmonic wave scattering in infinite complex media. Learn about the challenges posed by various media complexities, including equation types, physical characteristics, and geometries. Discover how this innovative method couples homogeneous or periodic half-space problems with inhomogeneous zones, offering advantages over traditional resolution techniques. Gain insights into the 2D implementation, involving a finite element representation within a square domain and four half-spaces. Understand the method's application in dissipative media, including its proven coercivity and convergence in discretization.
