Abstract
A method for making a composite magnetic-dielectric disc assembly includes forming a dielectric ceramic annular cylinder, forming a magnetic ceramic rod, assembling the magnetic ceramic rod coaxially inside the dielectric ceramic cylinder, joining the magnetic ceramic rod to the dielectric ceramic cylinder using an adhesive comprising a ceramic material to form a rod-and-cylinder assembly, and slicing the rod-and-cylinder assembly to form a plurality of composite magnetic-dielectric disc-shaped assemblies. The magnetic-dielectric disc assemblies can be used as components of, for example, circulators, isolators, or similar electrical assemblies.
