Personal profile
Personal Statement
I received the Ph.D. degree in physics from the University of Strathclyde, Glasgow, UK in 2012.
As a researcher, I have experience working on a variety of research projects including gyrotron travelling wave amplifiers, plasma filled microwave sources, microwave pulse compression and free electron lasers. I have led the development of gyro-TWAs in terms of design, computational simulation techniques and laboratory experimentation. I have carried out world-leading experiments of high power broadband mm-wave/THz amplifiers that have great potential in EPR/DNP and mm-wave wireless and satellite communications. I have successfully demonstrated a world-record 88-104GHz continuously tuneable, high power (10kW) Gyro-BWO experiment (2012), and a gyro-amplifier achieving 3.4kW with a 3dB instantaneous frequency bandwidth of at least 5.5GHz at W-band (2017).
Research Interests
Broadband, high power, mm-wave/terahertz gyrotron travelling wave amplifiers for next-generation magnetic resonance spectroscopy, telecommunications, security imaging and radar; Gyrotron backward wave oscillator; Conventional travelling wave amplifiers; Electron beam generation; Beam-wave interaction, Low-pressure gas discharge; Plasma filled high power microwave sources; Free electron lasers and pulsed power technologies.
