Analytic model of phononic crystals with local resonances
A simple analytic model is presented to describe the low-frequency effective mass densities of threecomponent phononic crystals with local resonances. We show that the effective mass densities can turn negative close to the local resonances. Expressions for the effective mass densities are derived for both threedimensional systems with coated spheres embedded in a host matrix, and two-dimension...

متن کاملTunable phononic crystals with anisotropic inclusions
We present a theoretical study on the tunability of phononic band gaps in two-dimensional phononic crystals consisting of various anisotropic cylinders in an isotropic host. A two-dimensional plane-wave expansion method was used to analyze the band diagrams of the phononic crystals; the anisotropic materials used in this work include cubic, hexagonal, trigonal, and tetragonal crystal systems. B...

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...
