| 摘 要： | 将开口谐振环作为加载单元,分析了含有开口谐振环结构非辐射介质波导的新型传输特性.由于异向介质的双各向异性效应,纵剖面磁波型和纵剖面电波型在此新型非辐射介质波导中的传输速度能够减慢,甚至达到零速度.对于波导中的能量关系也进行了分析,研究表明,在一定情况下,慢波传输将引起功率流动的增强.这些特性使得此新型非辐射介质波导更能满足小型化的设计要求.关键词：开口谐振环异向介质非辐射介质波导慢波传输

| Abstract: | Different dispersion properties are imparted to nonradiative dielectric (NRD) waveguides by split ring resonator metamaterials. Both longitudinal-section magnetic and longitudinal-section electric modes are capable of propagating very slowly due to the metamaterial bianisotropic effects, and can even approach zero velocity. Enhanced energy flow in the considered structure is also demonstrated under certain conditions. Finally, miniaturization of NRD waveguide based on these unusual properties is proposed. |
