- The article introduces a compact and polarization-insensitive Metamaterial energy harvester that operates efficiently in both S-band and C-band frequencies, addressing limitations of current designs that are often large and single-band.
- The harvester features a unique design with a rectangle strip and embedded hexagonal ring resonators, achieving impressive energy harvesting efficiencies of 97% at 3.5 GHz and 98% at 5.5 GHz.
- Experimental results from a 3 × 3 array confirm the design's reliability and effectiveness, highlighting its potential for diverse energy harvesting applications due to its high efficiency and small size (10 × 10 mm).
This article presents a novel real-time meta-material (MM) sensor based on a non-invasive method that operates in microwave frequency ranges at 8.524 GHz to measure blood glucose levels with quality factor 184 is designed and fabricated. A cross enclosed between two square shapes produces a strong interaction between glucose samples and electromagnetic waves.
