Abstract :
In this paper, an approach to couple electromagnetic surface integral equations and circuit simulation is presented. Terminals are defined that connect lumped circuit models to objects modeled with distributed electromagnetic simulation. A modified form of the charge-current continuity equation is proposed for connectivity at terminals. The resulting scheme enables simultaneous solution of electromagnetic integral equations for arbitrarily-shaped objects and SPICE-like modeling for lumped circuits, and permits design iterations and visualization of the interaction between the two domains.
