Synopses & Reviews
As wireless and telecommunications technologies evolve, essential high-frequency, compact electronic devices with increasing functionalities become focused topics in both academia and industry. Nonlinear hybrid electromagnetic systems are now widely used in RF/MMIC and optoelectronic circuits, where time-domain approaches for nonlinear systems have proved to be both effective and necessary. Incorporating the latest research results, this book provides a novel approach to circuit and field cosimulation. It bridges field and circuit solvers via a newly developed equivalent model. It forms a reference valuable to researchers, EDA developers, and practicing engineers.
The analysis of nonlinear hybrid electromagnetic systems poses significant challenges that essentially demand reliable numerical methods. In recent years, research has shown that finite-difference time-domain (FDTD) cosimulation techniques hold great potential for future designs and analyses of electrical systems.
Time-Domain Computer Analysis of Nonlinear Hybrid Systems summarizes and reviews more than 10 years of research in FDTD cosimulation. It first provides a basic overview of the electromagnetic theory, the link between field theory and circuit theory, transmission line theory, finite-difference approximation, and analog circuit simulation. The author then extends the basic theory of FDTD cosimulation to focus on techniques for time-domain field solving, analog circuit analysis, and integration of other lumped systems, such as n-port nonlinear circuits, into the field-solving scheme.
The numerical cosimulation methods described in this book and proven in various applications can effectively simulate hybrid circuits that other techniques cannot. By incorporating recent, new, and previously unpublished results, this book effectively represents the state of the art in FDTD techniques. More detailed studies are needed before the methods described are fully developed, but the discussions in this book build a good foundation for their future perfection.
