Antenna Development for Multifunctional Armor Applications Using Embedded Spin-Torque Nano-Oscillator (STNO) as a Microwave Detector

摘要

We proposed a novel regime of operation of a spin-torque diode, based on excitation of large-angle out-of-plane magnetization precession. CPW antenna was used as a feed line to the detector. The transmitting antenna was a commercial horn antenna. Ten spintronic detectors of microwave radiation were built and tested at TARDEC. We are in the process of integrating of these radar detectors into armor. Arrays of spintronic radiation-hard detectors have two important applications: analysis of frequencies of incoming signals and RF energy harvesting.
