The studies on mode interaction in gyrotrons had always been an active field of research
due to their theoretical and practical importance for better understanding of the underlying …

A periodic dielectric meta-surface output window was cold and hot tested to extend the
operating bandwidth and suppress the parasitic oscillations for a W-band wideband TE 01 …

Effects of the output window reflection instability on the performance of our designed-band
broadband gyrotron traveling wave tube (gyro-TWT) were studied by the simulation and hot …

This report presents an update of the experimental achievements published in the review
“State-of-the-Art of High-Power Gyro-Devices and Free Electron Masers”, Journal of Infrared …

In this article, a relativistic backward wave oscillator (RBWO) with sectional slow wave
structures (SWSs) has been designed to generate a long high-power microwave (HPM) …

A bidirectional machine learning (ML) method is proposed in this work to design a broad
bandwidth W-band meta-surface window (MSW) for a gyrotron traveling-wave tube (gyro …

We study a-band gyrotron operating at the second harmonics of the gyrofrequency with
reflections of the output radiation from the mismatched vacuum window. We observe the …
