Meta材料谐振行为的因果性研究
Physical Insights into the Resonance Behavior of Metamaterials
摘要
分析了横电磁波作用下开口谐振环双各向异性Meta材料，揭示了虚波数引起Meta材料谐振行为的事实.利用Floquet模将开口谐振环周期性结构的场分布展开,从电磁波传播角度得出了凋落模是引起Meta材料谐振行为的原因.对于来自主平面上的入射波,具有相同极化方式的Floquet透射模将发生谐振,并且电谐振和磁谐振将随着入射角的不同而改变.
Abstract
Bianisotropic split ring resonator (SRR) metamaterials under TEM waves are analyzed,which reveal that imaginary wave number leads to the SRR resonance.The field distribution over SRRs is expanded into Floquet modes.The metamaterial resonance is engendered by the evanescent modes.The resonance behavior happens in the transmitted modes with the same polarization as the wave incident in the main plane.And the electric and the magnetic resonances are varied with different incidence angle.
