Planar Slow Wave Structure Traveling Wave Tubes: Design, Fabrication and Experiment

Traveling wave tubes play a crucial role in fields like communication and broadcasting. Planar slow wave structure traveling wave tubes can settle the power limitation caused by the size reduction in traditional cylindrical-beam traveling wave tubes. Therefore, there are increasingly more researchers contributing to the development of planar slow wave structure traveling wave tubes.As a competitive candidate for 5G/6G communication, the planar slow wave structure traveling wave tubes are attracting a lot of attention. Yet there is not yet a book which specifically introduces the key points in the development of such a device, this is that book. Readers will learn how the planar slow wave structure traveling wave tubes work and how to design wideband, high efficiency, miniature millimetre wave and terahertz wave amplifiers.Key features: - Represents the first book introducing the planar traveling wave tube systematically. - Presents the first hot-test results of a ka-band planar traveling wave tube. - Illustrates several novel planar slow wave structures and schemes for millimetre wave and terahertz wave. - Details the fabrication process of different planar slow wave structures fabricated by different advanced manufacturing techniques.
