Tailored elastic surface to body wave umklapp conversion

HIGHLIGHTS

• who: Gregory J. Chaplain from the College University of London, London , AZ, UK have published the paper: Tailored elastic surface to body wave Umklapp conversion, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS of 12/01/2020
• what: In this article, by taking an elastic half-space, patterned by a graded resonant array of rods (Fig 1), the authors show that, one can obtain mode conversion from surface waves to compressional, P waves, and not just to shear, S waves in the bulk. Undeterred by its prevalence in quantum, discrete systems the authors demonstrate the efficacy . . .
