I am following the saw gas sensor example. When try to calculate S parameter, we need to fix the input power of the terminal and then perform a frequency domain study. I try to calculate the power from the terminal current and voltage by the equation for average AC power. But the result are not equal to the value I set to the terminal and it looks similar to the S parameter. Does my calculation give the output power? And How comsol apply the fixed power to the terminal in terms of the boundary conditions ?
