用于波导小型化的异向介质加载
Metamaterial Loadings for Waveguide Miniaturization
摘要：
我们表明，一个矩形金属波导加载的超材料元件组成的电场耦合（ELC）谐振器放置在侧壁可以运行的截止频率低于相应的空载波导。色散图表明，ELC负载波导中的传播模式对于TE和TM模式都是前向型的。我们还研究了同时加载ELC和开口环谐振器（SRR）的矩形金属波导的色散图和传输特性。这样的双负载波导可以支持前向波和后向波，并且提供对各个模式的传播特性的独立控制。
英文摘要：
We show that a rectangular metallic waveguide loaded with metamaterial elements consisting of electric-field coupled (ELC) resonators placed at the side walls can operate well below the cutoff frequency of the respective unloaded waveguide. The dispersion diagrams indicate that propagating modes in ELC-loaded waveguides are of forward-type for both TE and TM modes. We also study the dispersion diagram and transmission characteristics of rectangular metallic waveguides simultaneously loaded with ELCs and split ring resonators (SRRs). Such doubly-loaded waveguides can support both forward wave and backward waves, and provide independent control of the propagation characteristics for the respective modes.
