Abstract:

An analysis was made of the effect on the interaction fields outside the helix of a traveling-wave tube when a ferrite cylinder, d-c magnetized in the circumferential direction, is placed inside the helix. It is shown that the main effect is the introduction of a slowing factor for the phase velocity of the slow waves. This phase velocity is independent of the strength of the d-c magnetic field, but is proportional to 1 epsilonepsilon sub o to the 12 power, where epsilonepsilon sub o is the relative dielectric constant of the ferrite. It is also shown that the backward-wave modes are cut off for certain values of d-c magnetic field. Author
