Fast capacitance extraction for finite planar periodic structures using the generalized forward-backward method

摘要

In this paper, the generalized forward-backward (GFB) method is applied to the complex structures mentioned above. There are several schemes in the calculation of the impedance matrix. They all have pros and cons. One scheme may yield a faster computational time per iteration with more iteration to converge, while others may converge in less iteration with slower calculation time per iteration. Numerical examples are given in the later section to show the comparison.
