Abstrakti

Accumulation of electromagnetic field energy in classical passive structures such as resonators and reactive circuit elements is limited by the amplitude of time-harmonic external sources. In the steady-state regime, all incident power which is not absorbed is fully re-radiated (reflected), and the time-averaged stored energy is constant, even though the external source continuously supplies energy. Recently, we have shown that lossless objects can continuously accumulate energy if their properties are properly modulated in time. Here, we discuss this possibility and study means to release this accumulated energy in the desired moment or moments of time in form of pulses of the desired shape. Furthermore, we discuss a possibility of keeping the energy inside the load, turning off the incident wave and changing the modulation function of the load. Finally, instead of a single time-reactive element we consider a parallel time-varying LC circuit, that gives the same functionality, in addition allowing to engineer currents flowing through the load circuit elements.
