基于超材料的行波结构中的波能放大

Wave Energy Amplification in a Metamaterial based Traveling Wave Structure

Y. S. Tan, R. Seviour

摘要:

我们考虑了在超材料存在下粒子束和传播的电磁波之间的相互作用。我们发现,引入超材料引起了一种新的色散曲线,它确定了一个独特的波粒关系,通过超材料的频率依赖性和超材料的新能力,同时表现出负介电常数和磁导率。使用Madey定理的修改形式,我们发现,新的色散的超材料导致放大的电磁波功率。

英文摘要:

We consider the interaction between a particle beam and a propagating electromagnetic wave in the presence of a metamaterial. We show that the introduction of a metamaterial gives rise to a novel dispersion curve which determines a unique wave particle relationship, via the frequency dependence of the metamaterial and the novel ability of metamaterials to exhibit simultaneous negative permittivity and permeability. Using a modified form of Madey's theorem we find that the novel dispersion of the metamaterial leads to a amplification of the EM wave power.
