Integration of FDTD EM analysis and transient circuit simulation of RF systems

A combined transient simulation of a 300 MHz input, 20 MHz output RF radio transceiver system was performed using an industry standard FDTD simulator integrated with an open source state-variable based multi-physics simulator. The two simulators were interfaced at every time step and several nonline...

Description
Summary:A combined transient simulation of a 300 MHz input, 20 MHz output RF radio transceiver system was performed using an industry standard FDTD simulator integrated with an open source state-variable based multi-physics simulator. The two simulators were interfaced at every time step and several nonlinear iterations were performed at each step in order to ensure simulation convergence of the system which contains strong nonlinearities and a wide range of signal strengths at different points in the system.
