摘要

本文旨在研究和分析具有负横向磁导率的介质中的电磁传播,以及这如何导致一些物理现象,如后向波的出现和截止以下的传播。这项研究是通过使用开口环谐振器的超材料来完成的。研究表明,传输特定频带所需的波导尺寸可以缩小到其尺寸的一半。导出了在具有介电常数和负横向磁导率的两个平板存在的情况下波导内部传播的解析确定。最后,通过仿真展示了如何获得比文献中报道的损耗更低的后向波。

Electromagnetic Wave Propagation in Waveguide Loaded by Split Ring Resonator of Negative Permeability
This paper aims to study and analyze the electromagnetic propagation in media with negative transverse permeability and how this leads into some physical phenomena such as the appearance of backward waves and the propagation below cutoff. This study is done through the use of metamaterials of split ring resonators. It is shown that the waveguide dimensions needed to transmit a certain frequency band, can be miniaturized to half its dimension. The analytical determination of the propagation inside a waveguide in the presence of two slabs with dielectric permittivity and negative transverse permeability is derived. Finally it is shown by simulation, how to obtain a backward wave with lower loss than reported earlier in the literature.
