Abstract

Dielectric response of ferrite materials are important to design devices, like cores of inductors, transformers, and directional couplers. In this paper dielectric constant, loss factor, loss tangent and electrical conductivity of Ni-Zn ferrite materials have been measured, as a function of the frequency. The parallel plate capacitor method was employed in these measurements. The study of reflection and transmission coefficient at the air/ferrite interface have been achieved. Results are compared with electrodynamical models
