An equivalent circuit of Yee's cells is proposed for mixed electromagnetic and circuit simulations. Using the equivalent circuit, a mixed electromagnetic and circuit simulator can be developed, in which the electromagnetic field and circuit responses are simultaneously analyzed. Representing the electromagnetic system as a circuit, active and passive device models in a circuit simulator can be used for the mixed simulations without any modifications. Hence, the propose method is very useful for designing various electronic systems. To evaluate the mixed simulations with the equivalent circuit, two implementations with shared or distributed memory computer system are presented. In the numerical examples, we evaluate the performances of the prototype simulators to demonstrate the effectiveness.
