The Field of Microwave Magnetics [From the Guest Editor's Desk]

This issue of IEEE Microwave Magazine contains three focus articles covering nonreciprocal and tunable devices and circuits using novel magnetic materials, which provide essential functions for modern RF and microwave front ends. This multidisciplinary field involves materials, device physics, electromagnetics, circuit design, fabrication, and testing. Accordingly, microwave magnetics provides a rich landscape for scientific discovery and advanced device development with the potential of producing differentiating technologies that improve the performance of future RF and microwave systems.
