Abstract :
In this paper, the polynomial approximation of the COM parameters, as functions of multiple variables (including the frequency), is developed to accelerate dramatically fast simulation tools. These tools, based on the widely used COM analysis or matrix (P & T) modeling approaches, are needed to synthesize different kinds of leaky SAW-devices with good accuracy and in the shortest time.
