Zheng Gong (龚政)

I am now a Ph.D. student at Zhejiang University, advised by Prof. Xiao Lin and Prof. Hongsheng Chen.

I am interested in exploring novel light-matter interactions in artificially engineered photonic structures, such as random media, metamaterials, and photonic time crystals. On this basis, when moving charged particles (e.g., electrons) interact with these novel structures, free-electron radiation (e.g., Cherenkov radiation and transition radiation) can emerge. The main goal of my Ph.D. research is to discover new physics underlying electron-matter interactions and to pursue multi-dimensional manipulation of free-electron radiation in terms of its intensity, directionality, polarization, etc. To facilitate this goal, at this stage, I mainly use first-principle analytical calculations based on classical electromagnetic wave theory.
