摘要

描述了一种用等效磁偶极子模型表示印刷电路板(PCB)电磁发射的方法。从平面磁场近场扫描中推导出等效偶极子。利用矩量法(MoM)从模型中计算出近场和远场。在一定的建模近似下，该模型能够预测具有有限地平面的PCB空间中所有区域的辐射。

Modeling electromagnetic emissions from PCBs in free space using equivalent dipoles

A method for representing the electromagnetic emissions from a printed circuit board (PCB) using an equivalent magnetic dipole model is described. The equivalent dipoles are deduced from planar magnetic near-field scans. The near and far fields are calculated from the model using the Method of Moment (MoM). Under certain modeling approximations, the model is able to predict emissions in all the regions of space for a PCB with a finite ground plane.
