Localization and shaping of surface acoustic waves using PDMS posts: application for particle filtering and washing† [PDF]
We introduce a technique to control the position and effective area of the surface acoustic wave (SAW) acting on a fluid in a PDMS microchannel. The acoustic force can be localized at specific areas of the channels using a structured, ultra-thin PDMS ...

Determination of structure ordering parameters in subsurface layers of condensed state materials by AMD-methods [PDF]
The results of studies of solid-state materials using AMD-methods are presented. It is shown that, regardless of the type of structure of the studied materials and their nature, acoustic waves provide subsurface images.

Multilayer-graphene-based amplifier of surface acoustic waves
The amplification of surface acoustic waves (SAWs) by a multilayer graphene (MLG)-based amplifier is studied. The conductivity of massless carriers (electrons or holes) in graphene in an external drift electric field is calculated using Boltzmann’s ...
