Abstract

This work characterizes a ferromagnetic resonance identification (FMR-ID) tag with magnetic nanowires (MNWs) in an anodized aluminum oxide (AAO) template using a semiwireless configuration. The MNWs exhibit distinct ferromagnetic resonance (FMR) frequencies under DC magnetic field variation. A benchmark test using an electromagnet (Emag) to generate a controlled low DC field and vector network analyzer (VNA) operating from 15-30 GHz, produced 5-bit data. To demonstrate portability, Emag is replaced with Disc-shaped permanent magnets (Pmag) that also validate a 5-bit data response. A semiwireless detection setup (a horn antenna and a metamaterial patch antenna (MMPA)) with lower bandwidth successfully retrieved 2bits of the data. Pmag and Emag FMR responses have similar slopes to the Kittel equation with an offset of \sim 1GHz}, believed to be due to DC field differences. These predictable responses demonstrate the feasibility of a semi-wireless FMR-ID system for use in enhanced RFID security applications.
