Abstract

This study presents a flexible Ca-Zn ferrite-based metamaterial designed for microwave sensing application, particularly in the detection of dairy products. The design incorporates a split-ring resonator (SRR) unit cell fabricated on a flexible substrate synthesized through a sol–gel process, integrating PVA glue with Ca-Zn ferrite nanoparticles. Structural characterization through X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) confirmed the composite’s structural integrity and electromagnetic suitability. The MTM exhibited multi-frequency resonance at 2.4 GHz, 3.68 GHz, and 7 GHz, with the C-band resonance demonstrating high sensitivity for sensing applications. A key advantage of the design is its flexibility maintaining stable performance under bending angles up to 90 degrees without degrading performance. This work highlights the versatility and adaptability of the proposed metamaterial, making it a promising solution for microwave sensing technologies.

基于钙锌铁氧体纳米颗粒的传感柔性超材料的表征与分析

本研究提出了一种柔性钙锌铁氧体基超材料，设计用于微波传感应用，特别是在乳制品检测中。该设计集成了一个通过溶胶-凝胶工艺合成的柔性衬底上的分裂环谐振器（SRR）单元电池，将PVA胶与Ca-Zn铁氧体纳米颗粒结合在一起。通过x射线衍射（XRD）和场发射扫描电镜（FESEM）的结构表征证实了复合材料的结构完整性和电磁适用性。MTM在2.4 GHz、3.68 GHz和7 GHz处呈现多频共振，其中c波段共振在传感应用中表现出较高的灵敏度。该设计的一个关键优势是其灵活性，在高达90度的弯曲角度下保持稳定的性能，而不会降低性能。这项工作突出了所提出的超材料的多功能性和适应性，使其成为微波传感技术的一个有前途的解决方案。
