PhD student, 2016 intake

University: University of Nottingham, UK

Sponsor: University of Nottingham/NDEvR

Background: Undergraduate (2009) Masters (2014) in Electronics and Communication Engineering, Khulna University, Bangladesh.

The research is focused on advanced opto-acoustic transducer technology for the development of very high resolution ultrasonic imaging with potential applications ranging from NDE of materials and nano-engineered products through to live cell imaging. If the frequency goes up to the GHz region then the wavelength of the ultrasound becomes smaller than that of light and there is potential to create ultrasonic imaging systems with greater resolution than that of optical microscopes. The aim is to explore advanced optoacoustic transducer technology to improve the lateral resolution and control of nano-scale ultrasonic imaging.

We are eager to use photonic nanostructures that permit the generation and detection of sub-optical acoustic fields with optical techniques. We want to use metallic nanoshells, nanoparticles and metallic nanoarrays to overcome the limit of lateral resolution. A new state-of-the-art electron beam lithography tool will be installed for making nanostructures, a critical part of the project.
