Abstract :
This paper presents the results of the influence of several periodic magnetic field profiles applied on a typical electron beam existent in linear microwave tubes, such as traveling-wave tubes, from the well known trajectory equation. It was verified that a field profile like a square wave is the most indicated for the perfect focusing
