Abstract :
An integrated electromagnetic and circuit simulation environment is developed for the transient simulation of spatial power combining systems. The analysis incorporates surface modes, nonuniform excitation and full nonlinear effects. A state-variable approach makes the transient analysis very robust. The simulation tools are used to predict the performance of a 2 by 2 quasi-optical grid amplifier.
