High power microwave, millimeter wave
Interests
My research is focused on high-power micro/millimetre/THz waves with applications in clean energy (nuclear fusion and solar power generation), as well as the applications of THz/optical spectroscopy in astrochemistry, with collaborators at QMUL, in the UK and EU. I have been working on laboratory studies on formation and evolution of prebiotic molecules in the universe by performing complementary novel laboratory experiments at larger facilities, including the free-electron laser FELIX Laboratory (an EPSRC National Research Facility) in the Netherlands, the synchrotron radiation source ASTRID in Denmark, etc. I also work on high-power THz sources using vacuum electron devices (VEDs) driven by pseudospark-sourced electron beams.Publications
