Rainbow reflection and trapping for energy harvesting
Gregory J. Chaplain, Daniel Pajer, Jacopo M. De Ponti +1
Important distinctions are made between two related wave control mechanisms that act to spatially separate frequency components; these so-called rainbow mechanisms either slow or r…
Tailored elastic surface to body wave Umklapp conversion
Gregory J. Chaplain, Jacopo M. De Ponti, Andrea Colombi +7
Elastic waves guided along surfaces dominate applications in geophysics, ultrasonic inspection, mechanical vibration, and surface acoustic wave devices; precise manipulation of sur…
Ultra-thin, entirely flat, Umklapp lenses
Gregory J. Chaplain, Richard V. Craster
We design ultra-thin, entirely flat, dielectric lenses using crystal momentum transfer, so-called Umklapp processes, achieving the required wave control for a new mechanism of flat…
Flat Lensing by Graded Line Meta-arrays
Gregory J. Chaplain, Richard V. Craster
Motivated by flat lensing effects, now commonplace utilising negative refraction with finite slabs, we create negative refraction upon a graded line-array. We do so in the setting…
Rayleigh-Bloch, topological edge and interface waves for structured elastic plates
G. J. Chaplain, M. P. Makwana, R. V. Craster
Galvanised by the emergent fields of metamaterials and topological wave physics, there is currently much interest in controlling wave propagation along structured arrays, and inter…
