【摘要】 采用有限元方法,通过外加电流源求解周期结构中的有效电磁参数问题是一种通用的均匀化方法。该方法既可以适用禁带区域的计算,也可以适应有耗结构的计算。本文针对二维周期结构计算了有效电磁参数,并与文献[1]FDTD的计算结果进行了比较。更多还原

【Abstract】 It is a universal method of homogenization that using FEM(finite element method) and add a current source to solve the effective electromagnetic parameters in a periodic structure.This method not only can be applied to the calculation of the band gap of the area,can also adapt to the calculation of the lossy structure materials.In this paper,the calculation of effective electromagnetic parameters in a two-dimensional periodic structure is done,and the results were compared with the FDTD calculation results that were given in reference [1].更多还原
