| 摘 要： | 研究了开口金属环周期性阵列的磁谐振特性,推导了开口谐振环周期性阵列电磁特性分析的理论模型,提出了一个金属内外环的有效间对面积因子,并基于该因子修正了Pendry模型中磁谐振频率的表达式;数值算例表明改良的理论模型具有更高的预测准确度。本文提出的有效间对面积因子X=3,对于开口谐振环阵列这一典型的电磁结构的性能分析来说,其修正模型的指导性是可靠的。

| Abstract: | Corrected theoretical models are presented for structural electromagnetic performance analysis of metamate-rials with metal split-ring resonators. The prediction models about the metal split-ring resonators are theoretically derived.The magnetic resonance frequency expression of Pendry model is corrected by means of an effective surface-to-surface areafactor. The numerical examples show that these modified theoretical prediction models have higher accuracy. The effectivesurface-to-surface area factor X equals to three in this paper; and its guidance of these modified theoretical is reliable forstructural electromagnetic performance analysis of classic metamaterials with metal split-ring resonators. |
