基于半解析谱元法的各向异性介质PBG 结构传输特性的研究
Research on Transmission Characteristics of an Anisotropic Dielectric PBG Structures Based on Semianalytical Spectral Element Method
摘要
Abstract
Precise integration method combined with the spectral element is used to simulate and analyze the stop-band char-acteristic of anisotropic dielectric layer photonic band-gap (PBG)structures in waveguide.From the variational principle based on single variable corresponding to the vector wave equation,2-D spectral elements are employed to discretize the cross section of the layered structure,which contains anisotropic dielectric.Introducing the dual-variables,the variational principle is cast into the Hamil-tonian system,and then the high precision integration method is utilized to perform the stiff matrices.Compared with conventional fi-nite element method and semianalytical finite element method,numerical results demonstrate that the semianalytical spectral element method is more accurate and efficient for anisotropic PBG structures analysis,and it can achieve spectral accuracy with the increase of interpolation degrees of basis functions.关键词
