People that use piezoelectric transducers are interested in phased-array microphone, ultrasound equipment, ink-jet drop actuators, drug discovery, Sonar transducers, bio-imaging and acousto-bio-theraputics. Basically anyone who is trying...

Ultrasound Scattering Off a CylinderUltrasound Scattering Off a Cylinder

This 2D model studies the scattering of ultrasound waves off a cylindrical obstacle with different acoustic properties than those of the surrounding medium. The ultraweak variational formulation (UVWF) makes it possible to resolve the...
