二维磁光狭缝阵列的光传输特性

Light Transmission Through Two Dimensional Magneto-Optical Slit Array

Payman Pahlavan

AI总结:

本研究分析磁光材料在静磁场偏置下的张量介电常数特性,将其置于二维狭缝阵列中实现异常光透射,验证了该结构可作为磁调谐的高频率选择表面。

摘要:

本文采用模式匹配技术分析了TM波入射下狭缝阵列中磁光材料的金属特性,并通过全波仿真进行了验证。研究表明,这类材料在静磁场偏置下的张量介电常数可产生负等效介电常数,将其置于被称为狭缝阵列的周期性二维结构中时,会产生异常光透射效应。研究还发现,该结构可作为高频率选择表面,其特性可通过改变磁场偏置进行调谐。

英文摘要:

In this paper, metallic behavior of magneto optic materials in slit arrays under the incident of TM wave is analyzed by mode matching technique and confirmed by full wave simulations. It is shown that tensor electric permittivity of such materials under a static magnetic field bias can result in negative effective permittivity and if placed in a periodic two dimensional structure known as slit array, results in extraordinary optical transmission. It is also shown that this structure acts as a highly frequency selective surface tunable with magnetic bias change.
