We investigate the effect electrostatically-controlled aperiodicity has on the propagation of
flexural waves in two-component elastomeric films. We first determine the static response of …

In this work, we studied one-dimensional phononic structures for selective acoustic filtering.
The structures are composed of three and four materials which have different elastic …

Phononic crystal is a new kind of sound insulation material, which has an elastic wave gap.
When the elastic wave falls within the band gap, it will attenuate strongly in phononic crystal …

The study of elementary excitations in layered structures can be addressed via a Matrix
Sturm-Liouville Equation of motion. A stable numerical method to solve this ubiquitous …

We postulate a general Lagrangian density which leads to the equations of motion of the
well-known cases of the electromagnetic field, the theory of elasticity, and some other …

In this study, we have scrutinized the frequency gap generation by changing the geometrical
parameters of a one-dimensional phononic crystal. For this purpose, we have calculated the …

The phenomenon of selective diffraction is extended to in-plane elastic waves, and we
design surface corrugated periodic laminates that incorporate crystal momentum transfer …
