Measurement of nickel doped zinc oxide NPs resonance frequencies and electromagnetic properties in X-Band

Abstract In this work, the advantages of X-Band lead us to extract and study the electric and magnetic properties of Nickel (Ni) doped Zinc Oxide (ZnO) nanoparticles (NPs). So as to attain the proposed characteristics, waveguide measurement approach has been performed. And in order to extract the stated properties such as permittivity and permeability from the scattering parameters, Nicolson-Ross-Weir method has been utilized. Hence, both capacitance and inductance behaviors have been observed through the attained complex impedance considering the response of the Ni–ZnO NPs to the electromagnetic wave incident. Subsequently, results show that inductance, capacitance and resistance behaviors of Ni–ZnO NPs change around the two main resonance frequencies (8.767 GHz and 10.47 GHz). The attained magnetic susceptibility characteristic confirms that the Ni–ZnO NPs is ferromagnetic over the frequency of 8–9.746 GHz and paramagnetic up to 12.5 GHz.
