Ferrite helical devices

Abstract

The ability to manufacture a ferrite helix has been demonstrated. A ceramic processing method called viscous plastic processing was applied to microwave ferrites and the electrical and microwave properties of the ferrite were characterised. VPP allowed the realisation of highly complex geometries, specifically a FErrite heLIX. The applications of such a ferrite helix were also discussed, particularly uses such as resonance isolators and broad-band phase shifters. This work re-opens the field of helical ferrite devices, as a viable means of manufacture has been demonstrated.
