Effects of evanescent waves in phononic crystals with linear defects
3391 Periodic structures with linear defects have been traditionally analyzed with the ω(ï¿¿ k) methods with the supercell approximation. The presence of the linear defect introduces guided modes at frequencies in the band gap of the complete structure. This methodology only considers the propagating properties of the periodic system. In this work we report both theoretical predictions and expe...

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...
