Abstract:
A slow wave structure of a traveling wave tube is provided. The slow wave structure includes an input port, an output port, a first material, and a second material. The second material is mounted in the first material at periodic intervals in a direction of propagation of a radio frequency signal between the input port and the output port. The second material has a real part of permittivity that is negative and a real part of permeability that is positive at an operational frequency of the radio frequency signal.
