Modeling Absorbing Materials for EMI Mitigation
In this study, the parameters of magnetic absorbing materials were measured and used to predict their effectiveness at reducing total radiation power from a heat sink. The parameters of absorbing materials were measured using a transmission line method and fitted using the Debye model. By comparing S-parameters and power loss between a simulated and measured microstrip line, the fitted material parameters were validated. The heat sink model has also been investigated to determine the radiation mitigation with lossy materials.
