摘要

带电源总线的印刷电路板(pcb)的精确仿真一直是EMC工程师关注的问题。最近，新的电路提取工具CEMPIE-PEEC已被证明是印刷结构全波数值模拟的一种鲁棒方法。然而，在一些结构的模拟中观察到一些尖锐的奇共振。本文试图通过将CEMPIE-PEEC结果与积分- MoM -全波方法和差分- FDTD -全波方法进行比较，来深入了解这些奇异性的原因。

Investigation of potential resonances in CEMPIE-PEEC simulations of multilayered PCBs

Accurate simulations of printed circuit boards (PCBs) with power bus are of concern to EMC engineers. Recently the new circuit extraction tool CEMPIE-PEEC has proved to be a robust method for full-wave numerical modeling of printed structures. Nevertheless some sharp odd resonances have been observed in the simulation of some structures. This paper tries to give insights into the reasons of these singularities through comparisons of the CEMPIE-PEEC results with integral - MoM - and differential - FDTD - full-wave methods.
