Abstract:For most of the applications in the millimeter wave band, corresponding to Ka and higher-frequency bands, the relatively high atmospheric absorption necessitates the use of high-power sources. Here, a new approach for projecting an oversized beam tunnel in an overmoded structure by concentrating the axial field is demonstrated to meet the high-frequency and high-power demands of compact devices. Due to the enhanced high-current intense beam loading capability of the interaction circuit, a six-cavity Ka-band ex… Show more
