Abstract

Slow-wave structures are formed by the method of this invention in the form of a coupled-cavity structure. The coupled-cavity form of waveguide slow-wave structures is formed by wire electric discharge machining of disks from a solid rod of copper. The disks are supported in their desired positions by retained portions of the rod while the disks are brazed inside a cylindrical shell of copper. After brazing, the retained portions may be partially removed to form the completed slow-wave structure.
