Abstract :
The coaxial-ridged disk-loaded structure which is a new disk-loaded periodic system is presented and analyzed in this paper. As an all-metal slow-wave circuit, it has properties that can be used in high power traveling-wave tubes (TWT) and relativistic TWTs. The dispersion equation of this structure is derived by means of the field-matching method and it may be reduced to the dispersion of a series of coaxial structures, such as: the ridged disk-loaded structure, the Λ-like disk-loaded one and the disk-loaded one. The comparison of the dispersion characteristics between the structures above-mentioned is made. It is shown that the Λ-like disk-loaded structure has the weaker dispersion compared with the ridged disk-loaded one or the disk-loaded one.
