From: Tailoring the refractive index of impedance-matched ferrite composites
Plots of the relative real permittivity (εˊ) and permeability (μˊ) at 20 MHz as a function of the average NiZn ferrite particle size for a NiZn ferrite-PTFE composite with (a) 15% vol., (b) 30% vol., (c) 50% vol. and (d) 70% vol. loading of ferrite material. The average particle size and uncertainty were deduced from laser diffraction measurements.
