Metaclusters for the Full Control of Mechanical Waves
Pawel Packo, Andrew Norris, Dani Torrent
We present a new method for the control of waves based on inverse multiple scattering theory. Conceived as a generalization of the concept of metagrating, we call metaclusters to a…

The Inverse Grating Problem: Efficient Design of Anomalous Flexural Wave Reflectors and Refractors
Pawel Packo, Andrew N. Norris, Daniel Torrent
We present an extensive formulation of the inverse grating problem for exural waves, in which the energy of each diffracted mode is selected and the grating configuration is then o…
