| 摘 要： | 通过对加载异向非辐射介质波导(NRD)和H波导的全波分析,研究了此新型导波结构的传输特性。由于开口谐振环所引起的双各向异性效应,在双负参数条件下,纵剖面磁(LSM)波型和纵剖面电(LSE)波型将可能出现传播常数随频率增高而减小的异常高次模式,从而引起漏波。而在其它情况下,利用双各向异性效应却可以有效减少LSM和LSE波型的高次模漏波现象。尤其当异向介质取得单负参数时,此新型导波结构将能够完全抑制高次模漏波的出现。

| Abstract: | A rigorous full wave analysis of nonradiative dielectric waveguide and H-waveguide with split ring resonator metamaterials is presented to investigate the different dispersion properties. Due to the bianisotropic effects of metamaterials, some abnormal higher-order longitudinal-section magnetic(LSM) and longitudinal-section electric(LSE) modes may come into existence when metamaterials have double negative parameters. However, for other LSM/LSE modes, leakage can be reduced by utilizing the bianisotropic effects. In addition, when the metamaterials have negative permittivity, leakage elimination can be achieved. |
