A Xi-shaped meta structure, has been introduced in this paper. A modified split-ring resonator (MSRR) and a capacitive loaded strip (CLS) were used to achieve the left-handed property of the metamaterial. The structure was printed using silver metallic nanoparticle ink, using a very low-cost photo paper as a substrate material. Resonators were inkjet-printed using silver nanoparticle metallic ink on paper to make this metamaterial flexible. It is also free from any kind of chemical waste, which makes it eco-friendly. A double negative region from 8.72 GHz to 10.91 GHz (bandwidth of 2.19 GHz) in the X-band microwave spectra was been found. Figure of merit was also obtained to measure any loss in the double negative region. The simulated result was verified by the performance of the fabricated prototype. The total dimensions of the proposed structure were 0.29 × 0.29 × 0.007 . It is a promising unit cell because of its simplicity, cost-effectiveness, and easy fabrication process.
本文介绍了一种X形超材料结构。采用改进的分裂环谐振器（MSRR）和电容加载条（CLS）来实现超材料的左手特性。该结构使用银金属纳米颗粒墨水印刷，以非常低成本的相纸作为基底材料。谐振器通过银纳米颗粒金属墨水喷墨印刷在纸上，以使这种超材料具有柔韧性。它也没有任何化学废料，这使其具有环保性。在X波段微波频谱中发现了一个从8.72 GHz到10.91 GHz的双负区域（带宽为2.19 GHz）。还获得了品质因数以测量双负区域中的任何损耗。通过所制造原型的性能验证了模拟结果。所提出结构的总尺寸为0.29×0.29×0.007。由于其简单性、成本效益和易于制造的工艺，它是一种很有前景的单元结构。
