Analytical approximations for multiple scattering in one-dimensional waveguides with small inclusions
Mario Lázaro, Richard Wiltshaw, Richard Vaughan Craster +1
We propose a new model to approximate the wave response of waveguides containing an arbitrary number of small inclusions. The theory is developed to consider any one-dimensional wa…

Asymptotic approximations for Bloch waves and topological mode steering in a planar array of Neumann scatterers
Richard Wiltshaw, Richard V. Craster, Mehul P. Makwana
We study the canonical problem of wave scattering by periodic arrays, either of infinite or finite extent, of Neumann scatterers in the plane; the characteristic lengthscale of the…
