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.

A slow wave structure of a traveling wave tube comprising:
- an input port;
- an output port;
- a first material;
- and
- a second material, wherein 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, and 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.
A traveling wave tube comprising:
- a slow wave structure comprises
- an input port;
- an output port;
- a first material;
- and
- a second material, wherein the slow wave structure is configured to receive a radio frequency signal through the input port and to output an amplified radio frequency signal through the output port, wherein the radio frequency signal has an operational frequency;
- and
