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…
