摘要:

人工电磁材料的介电常数和磁导率具有可调节特性,当两者同时为负数时具有与传统材料相异的电磁特性,由于在自然界中并不存在介电常数和磁导率同时为负数的材料,目前国内外对人工电磁材料的等效实现与应用展开了广泛研究。在基于对偶传输线等效电路模型的基础上,提出了新型一维和两维平面结构人工电磁材料等效实现的单元模型;由于其采用非谐振结构的单元模型,具有低损耗、宽频带的逆斯涅尔折射效应和逆多普勒频移等特性。文章中给出了相应一维和两维等效人工电磁材料的计算分析与实验结果,其结果证明了该等效实现的正确性和可行性。

Abstract:

Based on the model of dual-transmission line, the permittivity ε and the permeability μ of artificial material can be adjusted by equivalent construction. When they are simultaneity negative, the artificial material has some fantastic electromagnetic characteristics. Because there is no double-negative materials existence in the nature world, the research on construction and applications of artificial material has widely developed all over the world. The novel unit structure of artificial material with one-dimension and two-dimension are presented, which have low-loss and wide frequency band. At last, the calculation and experiment results have proved the validity and feasibility of the construction.

Key words: material, equivalent realization, dual-transmission line, reversed Snell refraction
