论文摘要
大多数周期性的Terahertz（THZ）结构都需要基材来支撑；因此，发生其他吸收，导致低质量（Q）因子。不需要任何持有人或底物的独立结构显示出很高的灵活性和可伸缩性，因此非常适合应用。在这项工作中，提出并证明了由金属线编织网状组成的独立THZ金属结构。实验和数值结果表明，该金属网格可实现尖锐的fano样共振倾角，这在先前的研究中尚未发现。调查结果表明，由于其弯曲效果，高Q型Fano样共振倾角来自单层金属弯曲线。共振场纵向覆盖了由于编织网格的磁场体积较大，并从近场传感应用中获得了益处。
Most periodic terahertz (THz) structures need a substrate to support; thus, additional absorption occurs, resulting in a low quality (Q) factor. Free-standing structures that do not require any holder or substrate show high levels of flexibility and stretchability and hence are well-suited for THz applications. In this work, a free-standing THz metal structure consisting of metallic wire woven meshes is proposed and demonstrated. Experimental and numerical results exhibit that this metallic mesh achieves a sharp Fano-like resonance dip, which has not been found in previous studies. Investigation results indicate that the high Q Fano-like resonance dip comes from the single-layer metal bent wire because of its bending effect. The resonance field longitudinally covers the input and output end faces due to the large field volume of the woven meshes and benefits from near-field sensing applications.
