PhD Studentship in Thermodynamic Imaging to Improve the Reliability and Diagnostics of Anomalous Operation in High-Power Microwave Transistors
University of Surrey, United Kingdom
Deadline: 04 Dec 2015


The Advanced Technology Institute at the University of Surrey hosts researchers using fundamental and applied research for the design, manipulation and fabrication of optical and electronic devices/systems. Our researchers, from a diverse range of scientific backgrounds and backed by state-of-the-art research equipment and facilities, are currently designing materials, devices, and systems to address the grand challenges faced by society.


We are currently seeking to fill a PhD position in the area of multi-physics modelling of microwave power transistors. These transistors have important roles in mobile phone infrastructure, satellite communications, terrestrial broadcast, avionic and weather radar systems, and microwave backhaul, to name but just a few applications. Market demands for increased power and efficiency show no sign of abating and more circuit functions will be incorporated into a design. For the successful realization of high-frequency and high-power devices based on GaN, LDMOS, and GaAs technologies, we need to consider a comprehensive view of models, simulation methods, design techniques, all while incorporating the inevitable coupling that occurs between device physics, electromagnetics and the thermal environment.


The student will contribute to the development of and usage of thermoreflectance measurement techniques to gain insight into the operation of the internal transistor. In addition to measurements the student will be expected to be involved in detailed physical and numerical simulation using software packages like Agilent’s Advanced Design System, ANSYS’s HFSS, Sonnet’s em, as well as undertaking some practical measurements and programming in MATLAB. The student will work closely with an Industrial partner


Applicants are expected to have a first-class or 2:1 degree or equivalent in Electrical Engineering or Physics; a solid background in Microwave Engineering is an additional advantage.


Please email your CV and covering letter to: Dr. Peter H. Aaen, p.aaen@surrey.ac.uk, including transcripts of marks for your undergraduate and/or MSc with your application.
