Common Mode Mitigation by Applying Absorber with Genetic-Algorithm Optimized Cross-Section to Microstrip Pair
At the post-design stage, applying absorber to transmission lines is a cost-effective and efficient way to improve the EMI behavior of a product. This work presents an optimized shape of absorber that can be applied to a microstrip pair. The presented shape is an outcome of Genetic-Algorithm Optimization. It mitigates EMI by increasing common mode insertion loss of the microstrip pair while maintaining the differential mode signal integrity. Measurements are conducted to prove the superiority of the optimized shape of absorber.
