The effects of frequency, volume fraction of carbon black, and porosity on the complex permittivity of the epoxy-carbon black composites were investigated and the frequency dispersion behavior model for the complex permittivity was proposed. In the epoxy-carbon black composites, the frequency disper

The factors that influence the complex permeability of the epoxy-ferrite composite were investigated, and the frequency dispersion behavior model for the complex permeability was proposed. The complex permeability of the composite was measured by an impedance/gain phase analyzer and a network analyz
The complex permeability of ferrites is frequency dependent. The real part of the complex permeability deteriorates in a high frequency range and the imaginary part has a peak after starting the deterioration. This paper examines the possibility that the frequency characteristics for some ferrites c
## Abstract Three groups of NiβZn ferrite samples of the general formula; Ni~1β__x__~Zn~__x__~Y~__y__~Fe~2β__iy__~O~4~, were prepared by a doubleβsintering ceramic method, in an attempt to examine the solubility of yttrium ions on NiβZn ferrite. The theoretical values of the tetrahedral and the oct
