Far-field perfect imaging with time-modulated gratings
American Physical Society (2022-06-22)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 perfect image of an object in the far-field, ... -
Inverse Grating Problem: Efficient Design of Anomalous Flexural Wave Reflectors and Refractors
American Physical Society (2019-01-11)We present an extensive formulation of the inverse grating problem for flexural waves in which the energy of each diffracted mode is selected and the grating configuration is then obtained by our solving a linear system ... -
Metaclusters for the Full Control of Mechanical Waves
American Physical Society (2021)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 finite set of scatterers whose position ...
