A high frequency boundary element method for scattering by a class of multiple obstacles
Andrew Gibbs, Simon Chandler-Wilde, Stephen Langdon +1
We propose a boundary element method for problems of time-harmonic acoustic scattering by multiple obstacles in two dimensions, at least one of which is a convex polygon. By combin…
Numerically stable computation of embedding formulae for scattering by polygons
Andrew Gibbs, Stephen Langdon, Andrea Moiola
For problems of time-harmonic scattering by polygonal obstacles, embedding formulae provide a useful means of computing the far-field coefficient induced by any incident plane wave…
A hybrid numerical-asymptotic boundary element method for high frequency scattering by penetrable convex polygons
Samuel P. Groth, David P. Hewett, Stephen Langdon
We present a novel hybrid numerical-asymptotic boundary element method for high frequency acoustic and electromagnetic scattering by penetrable (dielectric) convex polygons. Our me…
Acoustic scattering: high frequency boundary element methods and unified transform methods
Simon N. Chandler-Wilde, Stephen Langdon
We describe some recent advances in the numerical solution of acoustic scattering problems. A major focus of the paper is the efficient solution of high frequency scattering proble…
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…
