Mr. Xingwang Bian | Beijing Vacuum Electronics Research Institute | China

Xingwang Bian is a senior-level researcher at the Beijing Vacuum Electronics Research Institute, working in the domain of vacuum electronics and high-frequency device engineering. He specializes in the research, design, and experimental development of traveling-wave tubes (TWTs) operating at millimeter-wave and terahertz (THz) frequencies — especially in the G-band. His work leverages advanced slow-wave structure designs, electron-beam systems, and optimized focusing/magnetics, aiming to push the power, bandwidth, and efficiency envelope for THz vacuum-electronic amplifiers.  Among his important contributions: he co-authored demonstration of a broadband continuous-wave G-band TWT providing multi-GHz bandwidth and tens of watts of output power — a promising step toward practical THz wireless communications and radar systems.  Bian has also been centrally involved in the development of pulsed G-band TWTs for radar applications, combining innovations in slow-wave structure (modified folded waveguide), high-current electron beams, and phase-velocity tapering to reach high output power levels (on the order of 100 W+ in pulsed operation) in a compact, vacuum-electronic device.  Through these efforts, Bian has helped advance what is arguably one of the leading THz-band vacuum-electronic technology pipelines from BVERI, contributing to both academic publications and applied-device development.  In sum: Bian is a specialized vacuum-electronics engineer/scientist whose expertise lies at the intersection of electromagnetic design, electron-beam physics, and high-frequency amplifier fabrication — with a clear emphasis on making high-power, wide-band, THz-band TWTs viable for radar, sensing, and communication applications.

Prof. Dr. Xiaoping Ren | Affiliated Hospital of Guangxi University | China

Dr. Xiaoping Ren is an internationally recognized surgeon and scientist known for pioneering breakthroughs in hand transplantation, spinal cord fusion, and head transplantation research. He designed the world’s first clinical hand allotransplantation model, contributed to the United States’ first hand transplant, and discovered key mechanisms such as RPCT and RCI. He led landmark achievements including the first mouse head transplant, the first human head-transplant surgical model, and multiple world-first advances in spinal cord fusion that restored neural continuity in animal studies. His work established him as a global leader in paralysis treatment and regenerative reconstruction. Dr. Ren has earned major international honors, including election to the Russian Academy of Natural Sciences, fellowship of the International College of Surgeons, and leadership roles such as Chief Scientist of the GICUP Alliance, supported by an extensive publication record across microsurgery, neurology, cardiology, and regenerative medicine.
