Wave propagation through a piezoelectric semiconductor slab sandwiched by two piezoelectric half-spaces
TL;DR: In this article, the authors analyzed the wave propagation through a piezoelectric semiconductor slab sandwiched by two polygonal half-spaces, and the results showed that the steady carrier density and the exterior biasing electric field have obvious influences on the reflection and transmission coefficients.
Journal ArticleDOI
In-plane elastic wave propagation in nanoscale periodic piezoelectric/piezomagnetic laminates
TL;DR: In this paper, the authors derived the equations of wave motion including the magneto-electro-mechanical coupling effect and solved them by taking the size effect into account and based on the nonlocal theory.

TL;DR: In this article, the relationship between bandgap efficiency and effective in-plane stiffness is explored, and a set of promising stiff and compliant optimized topologies are manufactured by water-jetting of an aluminum plate and experimentally tested to validate the calculated bandgap efficiencies and effective elastic properties.

Effect of interaction among the three time scales on the propagation characteristics of coupled waves in a piezoelectric semiconductor rod
Yuxing Liang,Yuantai Hu +1 more
TL;DR: Based on small fluctuation of carrier concentration, a linearly-algebra equation on velocities of coupled waves in a piezoelectric semiconductor rod is established and two wave velocity together with the attenuation effects are obtained hard on the heels as discussed by the authors.
