Efficient and accurate model order reduction of interconnect networks in the presence of incident fields

At high frequencies, interconnects can act as spurious antennas and result in signal degradation. An electromagnetic interference (EMI) analysis is therefore an important part of the design process. In this work an efficient method using projection based model order reduction is presented for efficient EMI analysis of high-speed interconnects. This approach builds on previous advances in model order reduction of transmission line networks and extends them to the case of lines excited by incident fields.
