The lumped-mass method is applied to study the propagation of elastic waves in two-
dimensional binary periodic systems, ie, periodic soft rubber/epoxy and vacuum/epoxy …

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 …

The authors study the propagation of Lamb waves in two-dimensional locally resonant
phononic-crystal plates, composed of periodic soft rubber fillers in epoxy host with a finite …

It is known that the transmission spectrum of the so-called locally resonant phononic crystal
can exhibit absolute sharp dips in the sonic frequency range due to the resonance scattering …

A lumped-mass method is introduced to study the propagation of elastic waves in two-

We investigated the absolute elastic wave band gaps in three-dimensional systems
consisting of steel inclusions embedded in plastic matrix. Numerical results show that the …

The acoustic properties of three-and two-dimensional phononic crystals consisting of hollow
spheres or cylinders are studied by means of numerical calculations by the layer-multiple …

Using the transfer matrix theory, we provided the band structure of flexural waves in an Euler-
Bernoulli beam with locally resonant structures, with two degrees of freedom, ie, a resonator …

The transmission of acoustic waves through centimeter-scale elastic and viscoelastic two-
dimensional silicone rubber/air phononic crystal structures is investigated theoretically and …

The propagation of acoustic waves in a phononic crystal slab consisting of piezoelectric
inclusions placed periodically in an isotropic host material is analyzed. Numerical examples …
