Shadow boundary effects in hybrid numerical-asymptotic methods for high frequency scattering
David P. Hewett
The hybrid numerical-asymptotic (HNA) approach aims to reduce the computational cost of conventional numerical methods for high frequency wave scattering problems by enriching the…
Wavenumber-explicit continuity and coercivity estimates in acoustic scattering by planar screens
S. N. Chandler-Wilde, D. P Hewett
We study the classical first-kind boundary integral equation reformulations of time-harmonic acoustic scattering by planar sound-soft (Dirichlet) and sound-hard (Neumann) screens.…
A high frequency boundary element method for scattering by a class of nonconvex obstacles
David P. Hewett, Simon N. Chandler-Wilde, Stephen Langdon +1
In this paper we propose and analyse a hybrid numerical-asymptotic boundary element method for the solution of problems of high frequency acoustic scattering by a class of sound-so…
A frequency-independent boundary element method for scattering by two-dimensional screens and apertures
David P. Hewett, Stephen Langdon, Simon N. Chandler-Wilde
We propose and analyse a hybrid numerical-asymptotic boundary element method for time-harmonic scattering of an incident plane wave by an arbitrary collinear array of sound-so…
