Throughout this book, we present a number of realistic yet simplified application examples. The simplification is made to convey important concepts without burdening the reader with unnecessary details. In this chapter, we present contributions from guest authors, who explain how they apply EMC simulation in an industrial context. Four contributions are featured, with insights from simulation experts at Robert Bosch Software and Engineering Services Ltd. India; BMW AG Germany; Meta Reality Labs, USA; and Analog Devices, USA.
