Phononic crystals and metamaterials are spatially periodic waveguides that may exhibit
wave attenuation bands and, therefore, can be applied as vibration attenuation devices. In …

Prediction and measurement of vibration power flow in structures are both important for
locating vibration sources and sinks and for confirming vibration propagating paths. From …

Vibration can also be modeled as waves propagating in an elastic waveguide. Phononic
crystals are periodic waveguides that may present Bragg scattering band gaps, frequency …

The analysis of standing waves, which correspond to the reactive part of the power in
structures, is not a sufficient tool for studying structural vibration problems. Indeed, the active …

Phononic crystals are periodic structures that exhibit frequency ranges where elastic waves
cannot propagate, also known as Bragg scattering band gaps. This study aims at simulating …
