The current communication deals with the investigation of sucrose concentration in aqueous solution using copper-based metamaterial structure at a wavelength of 1550 nm. In this article, 5 × 5 air holes are engraved on a copper-based metamaterial structure, which contains the different concentration of sucrose in aqueous solution. Further, the present structure manipulates with finite difference time domain (FDTD) technique to compute the sucrose concentration. Moreover, different losses (absorption loss, dispersion loss, propagation loss, and polarization loss) are measured for the same. Nevertheless, similar type of papers have been published, the present paper has a couple of benefits including the method of computation (FDTD) and the output variation (linear ship) with the concentration. Apart from this, the present research shows the error bar, which deals with an accurate measurement. Again a mathematical model is also obtained, which gives the relationship between the sucrose concentration and the output intensity. Further, output results declared that transmitted intensity varies linearly with the concentration of sucrose. Lastly, a feeble error in the commutation proclaims an accurate investigation of sucrose in their aqueous solution with the help of a photonic structure.

目前的通讯涉及使用铜基超材料结构在 1550 nm 波长下研究水溶液中的蔗糖浓度。在这篇文章中，在铜基超材料结构上雕刻了 5×5 个气孔，其中包含不同浓度的蔗糖水溶液。此外，本结构使用时域有限差分 (FDTD) 技术来计算蔗糖浓度。此外，还测量了不同的损耗（吸收损耗、色散损耗、传播损耗和极化损耗）。尽管如此，已经发表了类似类型的论文，本论文有几个好处，包括计算方法 (FDTD) 和随浓度的输出变化（线性船）。除此之外，目前的研究显示了误差条，它处理精确的测量。同样也获得了一个数学模型，它给出了蔗糖浓度和输出强度之间的关系。此外，输出结果表明透射强度随蔗糖浓度呈线性变化。最后，换向中的一个微弱错误表明在光子结构的帮助下对其水溶液中的蔗糖进行了准确的研究。
