"I use the virtual TDR function in MWS as the standard method for developing all of my high-performance broadband interconnects for electronic packages. TDR simulations are simply the best way to do this in my mind. I recently presented a paper at IMAPS 2008 in San Jose describing an connector/package design having high performance from 0 to 30GHz, which compared to previous attempts achieving perhaps at the most 22 GHz of bandwidth. This interconnect was designed using TDR and the MWS optimizer"

"New electronic systems accompany most of the technical innovations in automotive industry. In consequence of the growing number of electrical equipment the electromagnetic noise level is rising in automobiles. The increased electromagnetic emissions however raise the risk to violate EMC standards and perturb the functional integrity of new and existing electronic systems. Hence, mastering of potential EMC problems in new automobiles becomes increasingly important to the car industry. Numerical simulation is an important key for the detection and rejection of potential EMC problems early in the design process.."
