University of St. Andrews Researchers Use Ferrites to Create Faraday Rotators

 

An important component in many microwave and mm-wave systems is the isolator or circulator. University of St. Andrews researchers use permanently magnetized ferrite materials to construct quasi optical Faraday rotators (QOFRs) which can be used to make both isolators and circulators. These devices have very high performance and are a key enabling technology for many mm-wave systems. Construction of good devices requires detailed knowledge of the ferrite material, the dielectric matching layers and any adhesives involved. Learn more at the University of St. Andrews website.
