Dispersion assessment of three-dimensional Phononic Crystals using Laser Doppler Vibrometry
I. K. Tragazikis, D. A. Exarchos, P. T. Dalla +3
The elastodynamic response of finite 3D phononic structures is analyzed by means of comparing experimental findings obtained through a laser Doppler vibrometry-based methodology an…
Acoustic properties of colloidal crystals
I. E. Psarobas, R. Sainidou, N. Stefanou +1
We present a systematic study of the frequency band structure of acoustic waves in crystals consisting of nonoverlapping solid spheres in a fluid. We consider colloidal crystals co…
Viscoelastic response of sonic band-gap materials
I. E. Psarobas
A brief report is presented on the effect of viscoelastic losses in a high density contrast sonic band-gap material of close-packed rubber spheres in air. The scattering properties…
Phononic crystals with planar defects
I. E. Psarobas, N. Stefanou, A. Modinos
We study the effect of planar defects in phononic crystals of spherical scatterers. It is shown that a plane of impurity spheres introduces modes of vibration of the elastic field…
Scattering of elastic waves by periodic arrays of spherical bodies
I. E. Psarobas, N. Stefanou, A. Modinos
We develop a formalism for the calculation of the frequency band structure of a phononic crystal consisting of non-overlapping elastic spheres, characterized by Lamé coefficients w…
