Proceedings of the 17th IEEE International Vacuum Electronic Conference (IVEC-2016), Monterey, ISBN 978-1-4673-9217-4/16
The Seventeenth International Vacuum Electronics Conference (IVEC 2016) helded on 19-21 April 2016 in Monterey, California. With technical co-sponsorship from the IEEE Electron Devices Society (EDS), the conference provide a forum for scientists and engineers from around the globe to present the latest developments in vacuum electronics technology at frequencies ranging from the UHF to THz frequency bands.
IVEC was originally created in 2000 by merging the U.S. Power Tubes Conferences and the European Space Agency TWTA Workshops. Now a fully international conference, IVEC is held every other year in the U.S., and in Europe and Asia alternately every fourth year. After the successful and enjoyable meeting in Beijing, China in May, IVEC 2016 will return to its beautiful U.S. location in the city of Monterey.
Models of the cylindrical electrode for physiotherapy formed by a ribbed coaxial line were investigated and analyzed in this paper. The increasing towered the open end one, two or three longitudinal slots in the screen electrode were used to achieve the required distribution of the electromagnetic field in the surrounding tissue. The averaged dispersion characteristics of the fabricated models were measured by a network-analyzer in the frequency band 100...3000 MHz. The obtained data had been compared with characteristics of the ribbed coaxial line in the absence of the slots.
