Abstract

Rectangular, millimeter-scale complementary split ring resonators were fabricated, employing the so-called Computer Numerical Control method, combined with a home-built mechanical engraver. Their electromagnetic performance was thoroughly investigated with respect to their dimensions in the frequency regime between 2 and 9 GHz via combining experiments and corresponding theoretical simulations, wherein a considerably effective consistency was obtained. Moreover, their sensing response was extensively investigated against various aqueous solutions enriched with typical fertilizers used in agriculture, as well as detergents commonly used in every-day life. Corresponding experimental results evidently establish the capability of the studied metasurfaces as potential sensors against water pollution.

摘要

采用所谓的计算机数控方法，并结合自制的机械雕刻机，制作了矩形、毫米级互补分裂环谐振器。通过结合实验和相应的理论模拟，在2至9 GHz的频率范围内，对其电磁性能随尺寸的变化进行了深入研究，取得了相当有效的一致性。此外，还广泛研究了它们对富含农业常用典型肥料的各种水溶液以及日常生活中常用洗涤剂的传感响应。相应的实验结果清楚地证明了所研究的超表面作为潜在水污染传感器的能力。
