Published in 2021 at "Plasma Sources Science and Technology"

DOI: 10.1088/1361-6595/ac2350

Abstract: Coherent microwave scattering from laser-induced plasmas, including weakly ionized plasma, laser sparks, multiphoton ionization, and resonance enhanced multi-photon ionizations (radar REMPI) has achieved much successes in plasma, reactive and nonreactive flow diagnostics. Under illumination of… read more here.

Published in 2022 at "IEEE Geoscience and Remote Sensing Letters"

DOI: 10.1109/lgrs.2021.3103650

Abstract: The peak wave direction is a crucial parameter to quantify the physical characteristics of the ocean waves. For shipboard coherent microwave radar, the radar-illuminated space changes with the movement of the ship, and this fact… read more here.

Published in 2022 at "IEEE Transactions on Geoscience and Remote Sensing"

DOI: 10.1109/tgrs.2021.3138143

Abstract: Coherent microwave radar can provide reasonable wave heights, while wave periods are always overestimated. The “group-line” in the wavenumber–frequency spectrum is a possible mechanism to interpret the overestimation, but the previous model cannot fully explain… read more here.

Published in 2025 at "IEEE Transactions on Microwave Theory and Techniques"

DOI: 10.1109/tmtt.2025.3603746

Abstract: An actively mode-locked optoelectronic oscillator (AMOEO) is proposed and demonstrated to generate coherent microwave pulse trains with encoded pulse position and phase. Through injecting a square-wave pulse into the AMOEO, localized oscillation is built up… read more here.
