When designing interconnects for electronics, it only takes a few days to develop the basic structure and tune the impedance. However, reducing and removing resonances is typically a time-consuming, iterative process that can take weeks or months. With the use of eigenmodes and terminal coupling metrics, resonance reduction can be done in just a few days. I co-authored an article about this method. Please check it out and let me know what you think !
