Far-field Perfect Imaging with Time Modulated Gratings
Pawel Packo, Dani Torrent
We study the capabilities of time-modulated diffraction gratings as imaging devices. It is shown that a time-dependent but transversally homogeneous slab can be used to make a perf…
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…
Non-symmetric flexural wave scattering and one-way extreme absorption
Andrew N. Norris, Pawel Packo
The possibility of asymmetric absorption and reflection for flexural waves is demonstrated though analytical and numerical examples. We focus on the 1D case of flexural motion of 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…
