This book is a result of many years in active design work in the semiconductor industry. I started my career as a theoretical physicist working on dense matter theory and electromagnetic fields in an astrophysical environment. After a few years my interest turned towards integrated circuit design, where there were also electromagnetic fields, and I have been working in this field ever since. It is such a rich environment for the study of nature and mathematics and I am thrilled to be a part of it.
