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。 The magnetic resonance characteristics of the periodic array of open-ended metal rings are studied. The theoretical model of the electromagnetic characteristics of the periodic array of open-ended resonator rings is deduced. An effective area-to-area factor of the metal inner and outer rings is proposed. Based on this factor, the Pendry model Magnetic resonance frequency expression; Numerical examples show that the improved theoretical model has a higher prediction accuracy. The effective area-to-area factor, X = 3, is proposed in this paper. For the performance analysis of an open-ended resonant ring array, which is a typical electromagnetic structure, the guidance of the modified model is reliable.
