Research problems linked to this topic
- Surface acoustic waves (SAWs) have been used extensively for a variety of applications such as telecommunications, electronic devices and sensors.
- Acoustic emission (AE) is applied for the structural health evaluation of materials.
- Piezoelectric thin films on high acoustic velocity non piezoelectric substrates, such as ZnO and AlN, deposited on diamond or sapphire substrates, are attractive for high frequency and low-loss surface acoustic wave devices.
- Acoustic quality of closed spaces is an increasing concern all around the world, since noise pollution is one of the main nowadays pollutants, but also one of the less considered when building designing and construction.
- While most of the conventional acoustic liner which comprised of a micro-perforated panel (MPP) backed by a honeycomb structure shows good acoustic performance at high or medium frequency range, there is still very challenging for them at low-frequency range.
