Abstract :
This paper investigates the benefits of high permittivity and permeability RF materials on electromagnetic interference (EMI) performance of integrated circuit (IC) heatsinks. An analysis of lossy materials using Finite-Difference Time-Domain (FDTD) simulations is presented and findings are supported by experimental measurements carried out in both reverberation chamber (RC) and Semi-Anechoic Chamber (SAC) environments.
