Slow-wave structures´ performances of crossed-field devices

The most important problem, which represent of practical interest for specialists of UHF electronics and electrodynamics, is the design problem of M-type tubes slow-wave structure with preliminary determined characteristics, determination of limits (field tolerance) for slow-wave structure dimensions and etc. Among perspective solution it can mark branches coupled with creation computer-aided design which provide the operation of design programs to usual users. Now computer-aided design of M-type tubes and their components does not exist. In this connection the problem of the creation of similar systems is actual and is dictated by practical tasks. One of the component part such system: design of slow-wave structure is also shown in the paper.
