中文摘要：
提出了一种新型平面传输线型左手材料,并深入研究了其电磁特性。通过Bloch-Flo-quet理论推导了新型结构的色散曲线,通过色散曲线证明其为传输线型左手材料;提出了新型复合左右手传输线的等效电路模型,分别提取了平衡条件和非平衡条件下等效电路模型的参数值,由等效电路模型和电磁仿真得到的散射参数基本一致,证明了所提等效电路模型的正确性。提出的新型复合左右手传输线是平面结构,易于加工,且不需要缺陷地面结构,便于实际应用。
英文摘要：
A novel planar transmission - line style of left - handed metamaterial is proposed, and its electromagnetic characteristics are investigated. The dispersion curve of the proposed structure has been derived by using Bloch- Floquet theory and the CRLH TL is proved. Then the equivalent circuit model of the CRLH TL unit is provided, the parameters of the equivalent circuit model are extracted under balanced and unbalanced conditions by optimizing and synthesizing. The model is validated by comparing the circuit result with the simulator result. The novel planar transmission - line style of the left - banded metamaterial does not need defected ground structure, so it can be eas- ily designed and fabricated.
