pThis established textbook is didactically excellent and it unifies intuitiveness with extraordinary precision of its terminology and their derivation. It was developed as manuscript to teach students in electrical engineering, and has served to do so for thousands of students over 2 decades.p pDiscussed is the electromagnetic field theory and its mathematical methods. Maxwell's equations are presented and explained. It follows a detailed discussion of electrostatics, flux, magnetostatics, quasi stationary fields and electromagnetic fields. p pThe author presents how to apply numerical methods like finite differences, finite elements, boundary elements, image charge methods, and Monte-Carlo methods to field theory problems. He offers an outlook on fundamental issues in physics including quantum mechanics. Some of these issues are still unanswered questions. A chapter dedicated to the theory of special relativity, which allows to simplify a number of field theory problems, complements t
