SUMMARY:Computation and optimization of multiple wave scattering using bou
 ndary integral formulation - Kei MATSUSHIMA (University of Tokyo)

DESCRIPTION:In this talk\, I will introduce a numerical method for solving
  2-D exterior Helmholtz problems with multiple or periodic scatterers. The
  method is based on the multipole expansion (cylindrical wave expansion) w
 ith T-matrix\, which characterizes the scattering from a single obstacle. 
 A boundary integral formulation is used to compute the T-matrix of non-cir
 cular scatterers. After that\, I will talk about the design optimization (
 inverse design) of multiple scattering systems. Some numerical examples wi
 ll be provided to demonstrate that the proposed inverse-design method can 
 tailor multiple wave scattering.
