摘要

由电磁干扰(EMI)引起的非本意辐射一直是一个亟待解决的问题。其中，散热器的辐射是一个棘手的问题。本文提出了一种特征模态(CM)方法来识别散热器的辐射热点，并对辐射物理进行了解释。该方法采用基于积分方程(IE)的方法和特征模态分析，可以利用电流对结构各部分的辐射模态进行量化。因此，可以识别辐射热点。该方法便于CM方法的实际应用。

Characterizing Radiation Physics and EMI Mitigation for Heatsinks

Unintential radiation caused by EMI (electromag-netic interference) trouble-makers has always been a vital issue to deal with. Among them, the radiation from heatsinks is a tough problem. In this paper, a characteristic mode (CM) method is proposed to identify the radiation hot spots for heatsink, and to explain the radiation phtsics. With the proposed method, by applying integral-equation (IE) based method and characteristic mode analysis, the radiation modal from each part of the structure can be quantified using the current. Therefore, the radiation hot spot can be identified. This method facilitates the CM method in real applications.
