我们分析了复杂几何中的时谐麦克斯韦方程组。散射体Ω R包含高导电性的小线结构的周期性图案,单个元件具有开口环的形状。我们严格推导出散射体的有效方程,并提供有效介电常数和磁导率的公式。后者证明是频率相关的,并且对于适当的参数值具有负的真实的部分。这种磁性活动是左手超材料的关键特征。
We analyze the time harmonic Maxwell’s equations in a complex geometry. The scatterer Ω ⊂ R contains a periodic pattern of small wire structures of high conductivity, the single element has the shape of a split ring. We rigorously derive effective equations for the scatterer and provide formulas for the effective permittivity and permeability. The latter turns out to be frequency dependent and has a negative real part for appropriate parameter values. This magnetic activity is the key feature of a left-handed meta-material.
