谱域直线法及其在三维电磁场边值问题中的应用

The Spectral-Domain Method of Lines and Its Application in 3-D Electromagnetic Field Boundary Value Problems

本文将直线法和谱城法结合在一起而提出一种分析集成波导三维问题的混合方法——谱域直线法。这种方法吸取了谱域法存储空间小和直线法无相对收敛性的优点,因而是一种计算量小、收敛快和数值稳定的分析方法。对微带和悬置微带谐振器的分析结果与有关文献的数据一致,从而验证了方法的正确性和有效性。

Based on the spectral-domain method and the method of lines, a-mixed technique for the analysis of three dimensional electromagnetic field boundary value problems is presented, the technique takes the advantages of less memory space, less computation time and no relative convergence problems. Numerical results for microstrip resonator and suspended microstrip resonantor are in good agreement with the experimental data, thereby the accuracy of the mixed technique is verified.
