"EMI problems are not uncommon in high speed communication systems. As the system clock frequencies increases, so does the challenges in controlling the EMI in such systems. A connector is a very important part of a high speed communication system. Electromagnetic interference (EMI) is found to be tightly correlated to mode conversion: from differential-mode (DM) signals to common-mode (CM) currents and further to antenna-mode (AM) currents on the outside of cables or enclosures. Moreover, in such high speed systems, coupling to an adjacent cable-connector system is not uncommon. It is essential to understand and quantify this coupling path in order to mitigate the coupling. Though simulation based methods are widely used, such an approach is generally very time consuming and computationally resource hungry and an effort is made to quantify the coupling paths using measurement-simulation combinations with minimal simulation aid. This thesis presents a systematic approach to isolate and identify the different coupling paths in a high speed interface (in this case we show DVI), as well as identify which discontinuity (and hence the coupling path) is most critical to mitigate EMI. A transfer function based method is implemented to quantify the coupling in the connector cable system. The method developed in this study can be used for any high-speed interface in modern communication systems."--Abstract, page iii.
