ABSTRACT:
A process for determining the intrinsic magnetic permeability of elongated ferromagnetic elements and the electromagnetic properties of composites using such elements are disclosed. According to the process, an annular core or torus is produced, which torus is wound with ferromagnetic elements. The core is placed in a coaxial line, the properties of the torus are measured, and permeability of the elements and the properties of an equivalent composite for a given polarization are deduced from such measurement. Particular utility is found in the area of study of composite charges for use at microwave frequencies.
