摘要

本文提出了一种用时域近场扫描磁场测量推导出的等效偶极子模型来表示印刷电路板(PCB)电磁发射的方法。基本思想是用一组产生相同辐射场的无穷小偶极子代替PCB。时间相关等效偶极子的参数是通过直接拟合测量的近磁场来确定的。通过一个基本测试结构的仿真,验证了该方法的原理和准确性。然后通过模拟演示了扫描过程,尽管它很容易适用于实验。

Characterisation of radiated fields from PCBs in the time domain
In this paper, a method for representing electromagnetic emissions from a printed circuit board (PCB) using an equivalent dipole model deduced from time domain near-field scanning magnetic field measurements is proposed. The basic idea is to replace the PCB with a set of infinitesimal dipoles that generate the same radiated fields. Parameters of the time dependent equivalent dipoles are determined by directly fitting to the measured magnetic near fields. A simulation of a basic test structure is used to demonstrate the principle and accuracy of the approach. The scanning process is then demonstrated through simulation although it is readily applicable experimentally.
