ABSTRACT:
Slow-wave structures are formed by the method of this invention in the form of helical or coupled-cavity structures. A helical waveguide form of slow-wave structure is formed of a solid rod of copper machined with a deep, narrow helical groove. A copper sleeve is brazed to the periphery of the resulting helical thread to form a helically spiraling pathway about a solid axially centered and axially extending center portion. The center portion is then totally eroded away to form a slow wave structure having a helical radially-extending portion, or if only partially eroded with an inner helical axially-extending ridge to provide a helical axially-centered gap between adjacent ridges. The coupled-cavity forms of waveguide slow-wave structures are formed by machining disks from a solid rod of copper. The disks are supported in their desired positions by an axial retained portion of the rod until the disks are brazed inside a cylindrical shell of copper. After brazing, the axial retained portion is removed in whole or part to form the completed slow-wave structure.
