Field/Circuit Computational Modeling and Simulation Software Tool

The goal of this effort is to create a hybrid software product that combines a full wave electromagnetic solver with a sophisticated circuit simulator creating an engineering tool that is capable of simulating the complete system of complex electronic devices. This tool will be powerful asset for a wide variety of government and industry users for applications that combine field and circuit interaction such as radio design, co-site interference, and active tuning. Government applications could include the co-location of multiple transmitters on a vehicle or the impact of electromagnetic pulse on circuitry while industry users are interested in simulations such as the interaction of multiple antennas in cellular phone devices or the tuning of magnetic resonance imaging coils. In Phase I the concept was validated by simulating a multi-stage radio circuit connected to a monopole antenna. For Phase II the product will be refined to functionality of the circuit solver will be integrated into the full wave solver, creating a unified tool Validation of the solver will be provided against measurements such as the co-site interference problem of nearby radios. The effort will combine the multi-physics circuit simulator, fREEDA, with the full wave commercial software product, XFdtd.
