Focused ultrasound has attracted great attention in minimally invasive therapy, gene delivery, brain stimulation, etc. Frequency below 1 MHz has been identified preferable for high-efficacy drug delivery, gene transfection and neurostimulation due to minimized tissue heating and cell fragmentation. However, the poor spatial resolution of several millimeters and the large device diameter of ~25 mm of current sub-MHz ultrasound technology severely hinders its further applications for effective…

Analytical photoacoustic model of laser-induced ultrasound in a planar layered structure

A way of describing photoacoustic measurement techniques is listening to light. Another way is as sensor techniques for characterisation of materials by means of light and sound interacting with th

New n -Type Transparent Conducting Oxides

Most research to develop highly transparent and conductive thin films has focused on n -type semiconductors consisting of metal oxides. Historically, transparent conducting oxide (TCO) thin films

Transcranial cavitation-mediated ultrasound therapy at sub-MHz frequency via temporal interference modulation

Sub-megahertz transmission is not usually adopted in pre-clinical small animal experiments for focused ultrasound (FUS) brain therapy due to the large focal size. However, low frequency FUS is vital

The design of efficient broad-band piezoelectric transducers

A design method for acoustic thin disk transducers with high efficiency, broad bandwidth, and good impulse response is presented. This method is based on the use of quarter-wave matching layers

Written in 1985 as a text at the Naval Postgraduate School, this book provides a complete treatment of the fundamentals of transducer theory and The existing literature in the naval postgraduate

Photoacoustic shock wave emission and cavitation from structured optical fiber tips

Photoacoustic waves generated at the tip of an optical fiber consist of a compressive shock wave followed by tensile diffraction waves. These tensile waves overlap along the fiber axis and form a

Laser generation of high‐amplitude stress waves in materials

Stress‐wave environments generated at a confined surface by a pulsed laser were investigated. Experimental measurements and theoretical calculations demonstrated that confinement of the surface with
