Crosstalk Analysis for Nonparallel Transmission Lines using PEEC with a Dynamic Green's Function Formulation

摘要

The calculation of crosstalk on printed circuit boards (PCBs) can be critical to board design. Where coupling occurs between parallel sections, transmission line theory is sufficient. However, if the dominant sections are not parallel, a full-wave method, like PEEC can be used. In this paper a dynamic Green's function is utilized for the PEEC coefficient calculations. This paper includes a discussion of how analytic expressions for quasi-static PEEC calculations can be reused in the dynamic Green's function calculations, removing the need to derive new integration formulas. In addition, a subgridding approach is utilized to increase the integration accuracy.
