Edge-guided mode non-reciprocal circuit element for microwave energy

摘要

Isolators and asymmetrical circulators of the non-reciprocal type employing tapered conductors positioned upon a ferrimagnetic member wherein means are provided for creating a localized non-uniform D.C. magnetic field in the region of one edge of the tapered conductor and of a field strength sufficient to cause the ferrimagnetic slab to create a magnetic resonance condition within a predetermined frequency range.
