Abstract

Abstract: The finite element method incorporated with Floquet theorem is used to solve the 2-Dimentsional scattering problem of dielectric Electromagnetic Band-Gap(EBG) upon which a plane wave is oblique or perpendicular incident. By exploiting the periodicity of EBG, the computation complexity and required memories are efficiently reduced. Comparisons of reflection and transmission properties for a kind of dielectric Electromagnetic Crystals with different structure parameters are presented, which will be helpful to the design of the similar structures.

Key words: EBG, FEM, scattering, Floquet theorem

摘要： 采用有限元和Floquet定理相结合的方法，对不同参量的二维介质电磁带隙（EBG）结构的反射和传输特性进行了研究。利用EBG的周期性以较少的计算量和存储量，计算了平面波斜入射或正入射无限排列的二维介电EBG的散射特性。比较和分析了不同参数下EBG的反射和透射系数。研究结果有助于类似结构的实际设计。
