二维各向同性异向介质负折射特性仿真验证
Numerical verification of the NIR features for 2-D isotropic LHM
【摘要】 提出了一种工作在C波段的二维各向同性异向介质,相比于以往的二维异向介质,它除了具有二维各向同性的优点外,还具有带宽更宽,单元结构的尺寸更小,构造也更简单的特点.通过分别仿真验证异向介质的双负特性和负折射特性最终肯定上述异向介质的存在.
【Abstract】 A 2-D isotropic left-handed metamaterial (LHM) in C band with broad bandwidth and low loss is designed. The size of its unit cell is much smaller and configuration of its unit cell is symmetrical compared with previous LHM. The double negative (DNG) feature and the negative index of refraction (NIR) feature are verified by numerical simulation to prove the existence of the LHM. The numerical results show that the DNG and NIR phenomenon appear simultaneously as predicted.
