Abstract: We design magnetic material formed by USP resonators embedded in the host RT/Duroid 5870 • We compare NRW and FPHT retrieval methods for determining the complex permittivity and permeability of MUTs from the measurement of S-parameters • We find that both NRW and FPHT are matched for homogenous dielectric material • However, FPHT fixes the anti-resonant behavior in NRW for metamaterial inclusions • FPHT will be used as a tool to measure the effective permeability of the new hybrid composite magnetic material under development
