Claudio Paoloni received the degree cum laude in Electronic Engineering from the University of Rome “Sapienza”, Italy, in 1984. Since 2012, he has been Cockcroft Chair with the Engineering Department, Lancaster University, U.K. Since 2015, he has been the Head of Engineering Department. He is member at large of the Board of Governor of the IEEE Electron Devices Society, IEEE Senior member and Senior Fellow of the Higher Education Academy and Chair of the IEEE Electron Devices Society Vacuum Electronics Technical Committee (2017 – present). He was Guest Editor for the Special Issue of Transaction on Electron Devices on Vacuum Electronics (June 2014). He organised numerous international conferences and workshops, on vacuum electronics, millimetre wave and terahertz communications and technology. He is coordinator of two European Commission Horizon 2020 projects, TWEETHER “Travelling wave tube based w‐band wireless networks with high data rate distribution, spectrum & energy efficiency” and ULTRAWAVE “Ultra capacity wireless layer beyond 100 GHz based on millimeter wave Traveling Wave Tubes”.
He is author of more than 230 articles in international journals and conferences in the field of high frequency electronics, millimetre waves and THz vacuum electronics devices, wireless communications.
Tentative title. Evolution of traveling wave tubes towards sub-THz frequency
After more than 80 years, traveling wave tubes are still the enabling devices for high power at microwave.The rising interest to the millimetre wave spectrum beyond 70 GHz is stimulating a resurgence in TWT technology. The small wavelength at millimetre waves is dictating a redefinition of TWTs topologies and fabrication processes to replace the traditional helix not feasible above 70 GHz. An overview of the recent advancements in TWT technology and the impact on large scale applications such as novel wireless networks will be discussed.
