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.
