Local flow control by phononic subsurfaces over extended spatial domains
Armin Kianfar, Mahmoud I. Hussein
Local phonon motion underneath a surface interacting with a flow may cause the flow to passively stabilize, or destabilize, as desired within the region adjacent to the subsurface…
Phononic-subsurface flow stabilization by subwavelength locally resonant metamaterials
Armin Kianfar, Mahmoud I. Hussein
The interactions between a solid surface and a fluid flow underlie dynamical processes relevant to air, sea, and land vehicle performance and numerous other technologies. Key among…
Material vs. structure: Topological origins of band-gap truncation resonances in periodic structures
Matheus I. N. Rosa, Bruce L. Davis, Liao Liu +2
While resonant modes do not exist within band gaps in infinite periodic materials, they may appear as in-gap localized edge modes once the material is truncated to form a finite pe…
Metadamping in inertially amplified metamaterials: Trade-off between spatial attenuation and temporal attenuation
Mahmoud I. Hussein, Ibrahim Patrick, Arnab Banerjee +1
Metadamping is the phenomenon of either enhanced or diminished intrinsic dissipation in a material stemming from the material's internal structural dynamics. It has been previously…
Closed-form existence conditions for band-gap resonances in a finite periodic chain under general boundary conditions
Mary V. Bastawrous, Mahmoud I. Hussein
Bragg scattering in periodic media generates band gaps, frequency bands where waves attenuate rather than propagate. Yet, a finite periodic structure may exhibit resonance frequenc…
Broadband and intense sound transmission loss by a coupled-resonance acoustic metamaterial
David Roca, Mahmoud I. Hussein
The advent of acoustic metamaterials opened up a new frontier in the control of sound transmission. A key limitation, however, is that an acoustic metamaterial based on a single lo…
