Slow wave structure in microwave

WebbA compact standing-wave linac has been designed using S-band microwaves for medical and industrial applications. It uses a bi-periodic structure with constant impedance. It consists of a buncher section with three-cells and on-axis coupled cavities with nine-cells. The total length is 740.0 mm including the electron gun. Using SUPERFISH, HFSS Webbmoted the use of slow-wave structures (SWS) in new areas. Developed many years ago for microwave devices, such as traveling-wave and backward-wave tubes, SWS have shown many remarkable features
