摘要

利用有限元方法计算了由传导损耗和介电损耗引起的衰减常数。该方法考虑了印刷电路板环境中轨道间的趋肤效应和接近效应，并用于预测仿真所需的单位长度参数。结果表明，在典型的高速应用中，当频率接近1 GHz时，介电损耗与导电损耗相当。

Calculation of losses on printed circuit board by finite element method

The attenuation constant due to conduction and dielectric losses are calculated by using a finite-element approach. The approach takes into account the skin effect and proximity effect between tracks on a printed circuit board environment and is used to predict the per-unit-length parameters needed for simulation. Results show that for typical high-speed applications the dielectric losses are comparable to the conductive losses, for frequencies close to 1 GHz.<>
