    A New Approach to Coupled Interior-Exterior Helmholtz-Type Problems: Theory and Algorithms (2002)
    Details
    Publication Date: 2022-07-07
    Description: The work presents a new approach to the numerical solution of time-harmonic and time-dependent scattering problems. We replace Sommerfeld's radiation condition valid for the Helmholtz equation by a more general concept called pole condition. The pole condition is based on the Laplace transform of the exterior solution and allows a characterization of outgoing waves. Both new insight into the analysis of scattering problems as well as new numerical algorithms are obtained.
