Add to ORKGThere are two cases of the exterior problems of the Helmholtz equation. If lambda greater than or equal to 0 the bilinear form is coercive, and if lambda < 0 it is the scattering problem. We give a new approach of the infinite element method, which enables us to solve these exterior problems as well as corner problems. A numerical example of the scattering problem is given.Mathematics, AppliedMathematicsSCI(E)EI中国科学引文数据库(CSCD)3ARTICLE6657-6721
