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…
Generalized Bloch's theorem for viscous metamaterials: Dispersion and effective properties based on frequencies and wavenumbers that are simultaneously complex
Michael J. Frazier, Mahmoud I. Hussein
It is common for dispersion curves of damped periodic materials to be based on real frequencies versus complex wavenumbers or, conversely, real wavenumbers versus complex frequenci…
Trampoline metamaterial: Local resonance enhancement by springboards
Osama R. Bilal, Mahmoud I. Hussein
We investigate the dispersion characteristics of locally resonant elastic metamaterials formed by the erection of pillars on the solid regions in a plate patterned by a periodic ar…
Nanophononic metamaterial: Thermal conductivity reduction by local resonance
Bruce L. Davis, Mahmoud I. Hussein
We present the concept of a locally resonant nanophononic metamaterial for thermoelectric energy conversion. Our configuration, which is based on a silicon thin-film with a periodi…
Metadamping: An emergent phenomenon in dissipative metamaterials
Mahmoud I. Hussein, Michael J. Frazier
We theoretically demonstrate the concept of metadamping in dissipative metamaterials. We consider an infinite mass-spring chain with repeated local resonators and a statically equi…
Dispersive Elastodynamics of 1D Banded Materials and Structures: Design
M. I. Hussein, G. M. Hulbert, R. A. Scott
Within periodic materials and structures, wave scattering and dispersion occur across constituent material interfaces leading to a banded frequency response. In an earlier paper, t…
