WebApr 10, 2024 · We will prove the well-posedness of the direct scattering problem by showing that the sequence u j converges to a unique bounded solution of (2.1). To simplify notations we denote u ( x, λ, d) and G ( x, y, λ) by u ( λ) and G ( λ) respectively. Lemma 2.1 For λ ∈ R and j ≥ 0 one has (2.7) ‖ u j ( ± λ) ‖ L ∞ ( R 2) ≤ C ( 1 + 1 λ 1 / 4). Proof WebGiven the source f, the direct scattering problem is to determine the wave field u which satisfies (1)–(2). It is known that the direct scattering problem has a unique solution u ∈ H2(BR) for an 2010 Mathematics Subject Classification. 35R30, 78A46.

Newton Chapter 222 Accesses Part of the Texts and Monographs in Physics book series (TMP) Abstract We wish to solve the Schrodinger equation (\Delta + K^2 )\psi \; = \;V\psi , (1.1) where \Delta is the Laplacian in IR 3, with boundary conditions appropriate to scattering. WebJul 5, 2024 · The direct scattering problems in a bounded and connected region with Dirichlet, Neumann and Impedance boundary conditions were both studied in [ 6] by Colton and Kress. They used the boundary integral equation method and got their classical solutions. But the practical model may be more complex than this situation.
