Accumulation of electromagnetic field energy in lossless objects (resonators, metasurfaces, reactive circuit elements) is limited by the amplitude of time-harmonic external sources. In the steady-state regime, all incident power is fully re-radiated (reflected), and the stored energy does not increase in time, although the external source continuously supplies energy. Here, we show that lossless objects can continuously accumulate unlimited energy if their properties are made time-varying. Here we consider the simplest example of a reactive load of a transmission line and analytically derive the required time dependence of the load reactance for unlimited energy accumulation. We also prove that properly designing time-varying resonant circuits, one can arbitrarily engineer the time dependence of the current in the circuit fed by a given time-harmonic source. Finally, we discuss how this stored energy can be released in form of a tune-compressed pulse.
