Enhanced Polarization in Tadpole-Shaped (Ni, Al)/AlN Nanoparticles and Microwave Absorption at High Frequencies
By
Progress In Electromagnetics Research B, Vol. 34, 31-46, 2011
Abstract
Tadpole-shaped (Ni, Al)/AlN nanoparticles were synthesized via evaporating Ni-Al alloy in a mixed atmosphere of N2 and H2. As a counterpart, the spherical-shaped (Ni, Al)/Al2O3 The electromagnetic parameters of as-made nanoparticles/paraffin composites were then investigated in the frequency range of 2-18 GHz. Excellent microwave absorption can be obtained for the tadpole-shaped (Ni, Al)/AlN-paraffin composite at high frequencies and in a thin layer, which is thought to be the result of the enhanced polarization in the anisotropic tadpole-shaped nanoparticles. With the increasing of the composite thickness, the frequency of effective reflection loss shifts towards lower frequencies due to an improved impedance match and absorption.
