High frequency electromagnetic analysis - A historical perspective

The author has been involved in applied high frequency numerical electromagnetic analysis since the beginning of the field. Inspired by work on some of the first GaAs integrated circuits at GE Electronics Laboratory, Syracuse, NY, he learned electromagnetics with the intention of reducing and eliminating the multiple re-designs then required. This is the story, from the author’s personal perspective of how electromagnetic analysis has developed and matured from the very beginning until today, when it is now a required part of the microwave design process.
