New preconditioners for the Laplace and Helmholtz integral equations on open curves: analytical framework and numerical results
F Alouges, M Averseng - Numerische Mathematik, 2021 - Springer
Helmholtz wave scattering by open screens in 2D can be formulated as first-kind integral
equations which lead to ill-conditioned linear systems after discretization. We introduce two …
