On transitions in water wave propagation through consolidated to broken sea ice covers
Jordan P. A Pitt, Luke G. Bennetts
A theoretical model is used to study water waves propagating into and through a region containing thin floating ice, for ice covers transitioning from consolidated (large floe size…
RayleighBloch waves above the cut-off
Luke G. Bennetts, Malte A. Peter
Extensions of Rayleigh-Bloch waves above the cut-off frequency are studied via the discrete spectrum of a transfer operator for a generalised channel containing a single cylinder.…
Broadband control of water wave energy amplification in chirped arrays
Aidan J. Archer, Hugh A. Wolgamot, Jana Orszaghova +3
Water waves in natural environments are typically broadband, nonlinear and dynamic phenomena. Taking concepts developed for slow light in optics, we address the challenge of design…
Graded resonator arrays for spatial frequency separation and amplification of water waves
Luke G. Bennetts, Malte A. Peter, and Richard V. Craster
A structure capable of substantially amplifying water waves over a broad range of frequencies at selected locations is proposed. The structure consists of a small number of C-shape…
