Asymptotic behaviour of the scattering phase for non-trapping obstacles
Annales de l'Institut Fourier, Volume 32 (1982) no. 3, pp. 111-149

Let S(λ) be the scattering matrix related to the wave equation in the exterior of a non-trapping obstacle 𝒪⊂R n , n≥3 with Dirichlet or Neumann boundary conditions on ∂𝒪. The function s(λ), called scattering phase, is determined from the equality e -2πis(λ) = det S(λ). We show that s(λ) has an asymptotic expansion s(λ)∼∑ j=0 ∞ c j λ n-j as λ→+∞ and we compute the first three coefficients. Our result proves the conjecture of Majda and Ralston for non-trapping obstacles.

Soit S(λ) la matrice de diffusion, associée à l’équation des ondes dans l’extérieur d’un obstacle non-captif 𝒪⊂R n , n≥3 avec condition de Dirichlet ou Neumann sur ∂𝒪. La fonction s(λ), dite phase de diffusion, est déterminée par l’égalité e -2πis(λ) = det S(λ). On démontre que s(λ) admet un développement asymptotique s(λ)∼∑ j=0 ∞ c j λ n-j et on calcule les trois premiers coefficients. Notre résultat prouve la conjecture de Majda et Ralston pour des obstacles non-captifs.
