WebApr 27, 2015 · This paper deals with the numerical design of a directional invisibility cloak for backward scattered elastic waves propagating in a thin plate (A 0 Lamb waves). The directional cloak is based on a set of resonating beams that are attached perpendicular to the plate and are arranged at a sub-wavelength scale in ten concentric rings. WebApr 3, 2013 · An active elastodynamic cloak destructively interferes with an incident time harmonic in-plane (coupled compressional/shear) elastic wave to produce zero total elastic field over a finite spatial region. A method is described which explicitly predicts the source amplitudes of the active field.
