# Electromagnetic Field Computation by Network Methods

@inproceedings{Felsen2009ElectromagneticFC, title={Electromagnetic Field Computation by Network Methods}, author={Leopold B. Felsen and Mauro Mongiardo and Peter Russer}, year={2009} }

In this monograph, the authors propose a systematic and rigorous treatment of electromagnetic field representations in complex structures. The architecture suggested in this book accommodates use of different numerical methods as well as alternative Green's function representations in each of the subdomains resulting from a partitioning of the overall problem. The subdomains are regions of space where electromagnetic energy is stored and are described in terms of equivalent circuit…
