Abstract
A general theory has been developed to account for the effect of the dielectric loss of discrete dielectric rods on traveling wave tube helix loss. It is clearly shown that the influence of dielectric loss on attenuation constant is much larger at the millimeter frequency band than that at the microwave frequency band. The general theory developed here has been further conformed by comparing the results with those obtained elsewhere for some special cases.
