EMI Mitigation with Lossy Material at 10 GHz
In this paper, absorber material is utilized to mitigate an EMI problem in real hardware. For a complex and large system, identification of the source location is the first problem which must be solved to achieve electromagnetic interference (EMI) mitigation. Emission Source Microscopy (ESM) provides a powerful tool for locating the sources of radiation in GHz range on a printed circuit board (PCB). Once the source is identified, a suitable volume of the absorber material is placed on the source location to effectively reduce the radiated power at the frequency of interest. Further measurements of the total radiated power in a reverberation chamber are also performed to validate the EMI reduction method with the absorber material.
