Dear meep users I calculate total energy in a particular region, where there are plasmonic structures excited by a gaussian source, by using field_energy-in-box. According to my energy vs time graph, the total energy oscillates in time in every case, I mean in casd there are structures or not. How can this be physically true? When the computational cell is filled with a box of epsilon = 1, and there is only a point gaussian source, the total energy calculated by field-energy-in-box displays an oscillatory time evolution, rises towards the central frequency of the gaussian and then decreases, but oscillating at the same time. It is the total energy, so I guess one could not consider the transformation of energy forms. Thanks in advance. Bilge.
