光子技术研究院学术报告(67

题目:Surface Wave Imaging: with Sound and Light

报告人:Prof. Michael Geoffrey Somekh(The Hong Kong Polytechnic University)

主持人:李朝晖教授

时间:2016年5月6日上午9:30

地点:曾宪梓科学馆406会议室

 

报告摘要:

There are many deep analogies between different branches of physics and engineering. One that greatly influences some of my work is the connection between different types of surface waves both electromagnetic and ultrasonic. This talk will show the analogies between surface acoustic waves (Rayleigh waves) and electromagnetic surface waves (surface plasmons). I will look very briefly at the common mathematical basis for the waves and also look in more detail at the phenomenological similarities. I discuss the different applications of these waves. These range from monitoring biological processes, imaging cell membranes through to defect detection in materials using laser ultrasonics. This talk will briefly discuss of all these methods trying to show they all exist within a common framework. Finally, we will discuss the potential for other surface wave modes for a range of different applications.

 

报告人简介:

Prof. Michael Geoffrey Somekh Mike Somekh took his first degree from Oxford University in Metallurgy and Materials Science. He then completed his PhD in Microwave Electronics from Department of Physics, University of Lancaster in 1981. He then returned to Oxford to work on contrast mechanisms in Acoustic Microscopy first as a research associate then as an EPSRC Research Fellow. He then joined University College London as lecturer and Director of the Wolfson Unit for micro-NDE. In 1989 he joined the University of Nottingham as Senior Lecturer and was promoted to Reader (1992) and Professor of Optical Engineering (1994). While at Nottingham he founded the Applied Optics Group, now one of the largest in the UK, and become director of the IBIOS the Institute of Biophysics Imaging and Optical Science.

His research interests are novel microscopy, imaging sensors and laser ultrasonics. He is Chair Professor in Biophotonics and Head of EIE, where he is establishing a new activity in Bioimaging and Sensors to mesh with the existing strengths of the department.

Mike was elected to the Royal Academy of Engineering (the UK engineering Academy) in 2012 in recognition of his interdisciplinary work. In addition to his post at PolyU he is an honorary professor at the University of Nottingham and Zhejiang University, Hangzhou.
