将电感推广到非准静态电磁场振荡的情况,在考虑由细线环超原子构成的无线电力传输和射频超材料时似乎是有益的。当处理包含电流的大型相互作用环系统时,在存在延迟的情况下,计算效率和精度至关重要。在这项工作中,我们推导了这种广义电感的级数展开,并提出了一种高效数值近似的方法。文中提供了两个环对的电感收敛性以及超材料样品散射消光效率的示例。
英文摘要
Generalization of the inductance to the case of non-quasistatic electromagnetic field oscillations appears to be fruitful when considering wireless power transfer and RF metamaterials consisting of thin wire loop meta-atoms. When dealing with large systems of interacting loops carrying currents, efficiency and precision of calculation in the presence of retardation is crucial. In this work, we derive a series expansion of such generalized inductance and propose a way for its efficient numerical approximation. Illustrative examples are provided both for inductance convergence of a pair of two loops and extinction efficiency for scattering by metamaterial samples.
