In Magnetic Particle Imaging, the behavior of the system matrix energy in dependence of the frequency components has been investigated and relations have been observed. Due to the lack of a closed-form expression for the 2- or 3-dimensional system function, no expression for the energy has been obtained thus far. In this work, we use the recently found expression for the 2-dimensional system function to derive an upper bound for the energy of the 2-dimensional system function as a function of the frequency components. The comparison of the upper bound with the energy of a simulated system matrix confirms the results.
