Abstract :
It is well known that the two-port reactance function of a lossless system is uniquely related to the stored energy in the system. It is here demonstrated that the analogous reactance function for an active and/or lossy system characterizes the power exchange between the system and its surroundings. It is pointed out that the true stored energy of such a system cannot be uniquely related to its two-port impedance function.
