Abstract Three metamaterial samples were simulated, numerically analyzed, and fabricated with different resonator lengths on similar unit cells. According to the results in addition to conventional LC resonance of the resonator, standing wave resonance was also observed within the resonator-dielectric-grounded back wire waveguide. We observed that the orientation of the sides of this waveguide relative to the polarization of the incident electromagnetic wave has a direct effect on the resonant frequency. The best asymmetric shape of the resonator with the minimum reflection coefficient in a wide frequency range of about 5.5 GHz with only 3% of reflection was introduced. According to the results, metamaterial polarizers and optical filters can be produced based on the standing wave resonances.

基于LC和驻波共振的宽带非对称微波超材料

摘要 对三个超材料样品进行了模拟、数值分​​析，并在相似的晶胞上制造了不同长度的谐振器。根据结果​​，除了谐振器的常规 LC 谐振外，还在谐振器-电介质接地的背线波导内观察到驻波谐振。我们观察到该波导的侧面相对于入射电磁波的极化方向对谐振频率有直接影响。介绍了在大约 5.5 GHz 的宽频率范围内反射系数最小且反射率仅为 3% 的谐振器的最佳非对称形状。根据结果​​，可以基于驻波共振生产超材料偏振器和滤光器。
