Time Domain Electromagnetic / Circuit Co-Simulation

Using a new electromagnetic/circuit co-simulation capability based on the finite-difference time-domain (FDTD) method, the process of importing broadband circuit models into an electromagnetic simulation project, optimizing the overall design, and calculating important quantities such as S-parameters, radiation patterns, and system efficiency is demonstrated in this MicroApps presentation from IMS 2018.

The ability to import complex circuits into Remcom's full wave electromagnetic simulation product, XFdtd, allows scientists and engineers to incorporate accurate broadband models of real world circuit components into their electromagnetic designs.  Using these circuit models increases the accuracy of dissipated power and system efficiency calculations.  The need to iterate between multiple electromagnetic and circuit software tools during a project is also reduced, thus saving companies time and money.
