Two-dimensional phononic crystals studied using a variational method: Application to lattices of locally resonant materials
A variational method is introduced to study the propagation of elastic waves in two-dimensional periodic systems. First, it has been applied to a binary system consisting of an array of high-density cylinders in an epoxy background, where the advantages of the method are pointing out in regard with the well-known plane-wave expansion formalism. Second, a comprehensive study is performed for the...
متن کاملInvestigation of Locally Resonant Absorption of Phononic Glass
This work experimentally studied locally resonant absorption mechanism in phononic glass. From these results, we attributed its strong sound attenuation to its locally resonant units and its broadband absorption to its networked structure. These experiments also indicated that the porosity of the phononic glass must be tuned to achieve the best sound absorption at given frequencies.
متن کاملMagnetic-Sphere-Based Phononic Crystals
Periodic arrays in one, two, and three dimensions, made of magnetic spheres embedded in a fluid matrix, are considered in this study and utilized as phononic structures. The propagation of acoustic waves through these structures is analyzed experimentally, in lowand high-frequency region, via laser vibrometry, as well as standard underwater acoustic measurements. A first comparison to theoretic...
