Abstract

In this article, visualization of noise coupling paths is proposed and verified. The coupling coefficient ( CC ) is derived based on the Reciprocity theorem and time-average coupled power, which represents the contribution of each spatial point to the coupled power. The physical meaning of CC is demonstrated by relating the integrations of CC in a volume space occupied by absorbers to the coupled power being suppressed by the absorbers. The proposed method is applied to a practical device and the identified dominant coupling paths are experimentally verified.

基于互易定理的噪声耦合路径可视化

本文提出并验证了噪声耦合路径的可视化。耦合系数（CC）是根据互易定理和时间平均耦合功率得出的，它代表了每个空间点对耦合功率的贡献。通过将吸收体所占体积空间中的 CC 积分与吸收体所抑制的耦合功率联系起来，证明了 CC 的物理意义。我们将所提出的方法应用于一个实际设备，并通过实验验证了所确定的主要耦合路径。
