摘要：

We investigate the effect of negative materials used as support structures for helix travelling wave tubes (TWTs). Analysis is carried out with materials having negative permittivity or negative permeability and compared with the positive dielectric support materials. The work attempts to focus on the dispersion relation and interaction impedance as a measure to check for the feasibility of using negative materials in TWT.
