Novel Free Space Microwave Detector Based on Metamaterials and Spintronics Devices
- Detailed Technology Description
- This invention presents a microwave detectorbased on metamaterials (e.g. split ring resonators) and its combination withspintronic devices (e.g. magnetic tunnel junctions). Due to the miniature sizeand strong resonances in microwave frequency range, split ring resonators (SRR)can be successfully applied in microwave imaging. Furthermore, due to someproperties of spintronic devices, the coupling between them and SRR makes aunique free space microwave detector with several advantages over regularmicrowave detectors. Pre-existingtechnology of microwave detection is using antennas to collect microwave,waveguide to transmit and semiconductor diodes to detect the microwave. Whilein this invention, the waveguide part is eliminated. Moreover, the detection isresonance based, thus having a strong frequency sensitivity. This system has an advantage ofbetter spatial resolution than regular antenna arrays for microwave imaging dueto the use of SRR. Additionally, microwave phase may also bemeasured with this device when a coplanar feed in circuit is added.
