Field/Circuit Computational Modeling and Simulation Software Tool

With ever sophisticated antenna and transceiver designs, the traditional separation between antennas and circuits has become blurred. Many antenna designs now contain integrated circuitry and have circuitry that includes active and passive devices with nonlinear and time-varying characteristics. In order to design such antennas and conduct a correct a thorough investigation of proposed designs, it is necessary to model both the electromagnetic effects and the circuitry. The proposed tool will be able to model the high fidelity time domain of radio transceivers circuits with both nonlinear and dynamic characteristics. Thus the goal of this proposed project is to integrate proven circuit modeling tools with electromagnetic modeling and simulation tools. The proposed tool will support not only radiated energy but also the effects of external fields such as co-site interference on the circuitry. The proposed tool shall extend two widely used and proven software packages: fREEDA, a circuit simulator with its schematic capture engine ifREEDA, and XFdtd, a finite difference time domain electromagnetic simulator.
