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.

🎓 Early Academic Pursuits

Dr. A. Paksa’s academic journey in the field of medical entomology began with a strong foundation at the Tehran University of Medical Sciences, where he pursued and successfully completed a Bachelor’s, Master’s, and Ph.D. in Medical Entomology and Vector Control. His early academic years were marked by a deep interest in public health and vector-borne diseases, which naturally progressed into a lifelong dedication to research and fieldwork. His Master’s thesis focused on detecting resistance mechanisms to organophosphate and carbamate insecticides in Blattella germanica (German cockroach) collected from Tehran hospitals. Later, during his Ph.D., he conducted an extensive study on the genetic diversity, Wolbachia infection, and ecological features of Aedes caspius and Aedes vexans, both of which are significant vectors for arboviruses in Iran. This early research demonstrated his capability in both laboratory and field settings, laying the groundwork for his future contributions to medical entomology and public health.
