Computational Framework for Mixed Electromagnetic and Electrical Circuit Simulation

In this SBIR project, we propose the concept of an integrated simulation environment for mixed analysis of electromagnetic structures and electrical circuits. The proposed framework not only provides a unified user interface for simulations of different type (EM and circuit), but it also creates a self-consistent conduit for hybrid electromagnetic simulations using different types of numerical techniques within a convenient and user friendly visual interface. Both frequency domain and time domain electromagnetic and circuit simulator will be included in the framework. The EM simulation engines will include the Method of Moments, Finite Element Method and Finite Difference Time Domain method. The circuit simulation engines will include Harmonic Balance and SPICE-type time domain simulators. The framework will accommodate parallel simulation codes for high performance computing (HPC) platforms. The graphical user interface of the framework will provide extensive geometry and schematic capture utilities as well as data visualization tools.
