Diffraction by a right-angled impedance wedge: an edge source formulation
David P. Hewett, Aaron Morris
This paper concerns the frequency domain problem of diffraction of a plane wave incident on an infinite right-angled wedge on which impedance (absorbing) boundary conditions are im…

Tangent ray diffraction and the Pekeris caret function
David Peter Hewett
We study the classical problem of high frequency scattering of an incident plane wave by a smooth convex two-dimensional body. We present a new integral representation of the leadi…

Acoustic scattering by fractal screens: mathematical formulations and wavenumber-explicit continuity and coercivity estimates
Simon N. Chandler-Wilde, David P. Hewett
We consider time-harmonic acoustic scattering by planar sound-soft (Dirichlet) and sound-hard (Neumann) screens. In contrast to previous studies, in which the domain occupied by th…
