Abstract

This talk will present some recent progresses on the fast and high-order boundary integral equation solvers for solving the frequency-domain wave scattering problems. Some regularization techniques and the associated theoretical analysis of the singular integral operators are developed to reduce the singular integrals to combinations of weakly-singular integral operators and surface differential operators whose numerical evaluations can be achieved by means of a newly developed Chebyshev-based rectangular-polar solver. This provides a novel CAD-CAE approach which can avoid the evaluation of computational mesh and can efficiently treat different complex CAD geometries. Numerical examples will be presented to show the accuracy and efficiency of the proposed solvers.
