Abstract

We present the results of a theoretical study of the electrodynamic characteristics of fast and slow electromagnetic waves (EMWs) propagating in a metamaterial consisting of a ferromagnetic film inside which there is a periodic lattice of thin metal wires. The ferromagnetic thin-film metamaterial possesses the properties of a left-handed medium at frequencies of slow electromagnetic waves. In a ferromagnetic metamaterial, in comparison with a conventional ferromagnetic film, the cutoff frequencies of fast and slow electromagnetic waves shift to a higher frequency range and the electromagnetic waves themselves become very slow.

纵向磁化薄膜铁磁超材料中的快电磁波和慢电磁波

摘要

我们介绍了在由铁磁膜组成的超材料中传播的快慢电磁波（EMW）的电动力学特性的理论研究的结果，在超材料内部有金属细线的周期性晶格。铁磁薄膜超材料在慢电磁波的频率下具有左手介质的特性。在铁磁超材料中，与常规铁磁膜相比，快电磁波和慢电磁波的截止频率移至更高的频率范围，并且电磁波本身变得非常慢。
