High frequency asymptotic solutions of the reduced wave equation on infinite regions with non-convex boundaries
The asymptotic behavior as λ→∞ of the function U(x,λ) that satisfies the reduced wave equation Lλ[U]=∇⋅(E(x)∇U)+λ2N2(x)U=0 on an infinite 3-dimensional region, a Dirichlet condition on ∂V , and an outgoing radiation condition is investigated. A function UN(x,λ) is constructed that is a global appr...
