Losses are often the impairing feature of metamaterial true time delay line devices. In this study, the authors analytically demonstrate that ohmics losses in this kind of structures as well as impedance mismatch depend on the bandwidth. These results allow to consider wide band application for radar systems. It is verified experimentally that metamaterial delay line devices are fitted for wide band delay line applications for they allow low insertion losses, low return loss and tunable delay.

损耗不会阻止宽带超材料真实时间延迟线的应用，GaAs MMIC实验验证

损失通常是超材料真实延时线设备的削弱特征。在这项研究中，作者通过分析证明了这种结构中的欧姆损耗以及阻抗失配取决于带宽。这些结果可以考虑在雷达系统的宽带应用。实验证明，超材料延迟线设备适合宽带延迟线应用，因为它们允许低插入损耗，低回波损耗和可调延迟。
