title = "Bypassing Rozanov's bound for short-time pulses",
abstract = "Here, we explore the scattering and absorption efficiency of a short-time pulsed wave that impinges on an absorbing layer that consists of a time-varying layer that is backed by an ideal conductor (PEC). The analysis is done by solving in-time the Green's function of the TL equivalent of the layered system. Its numerical evaluation is accelerated by using the fact that its only contribution comes from discrete spectrum waves, and thus any spectral integration can be replaced by an efficient summation. Due to the switching process the absorption is enhanced in comparison to Rozanov's bound that was derived for linear and time-invariant (LTI) wave systems. We demonstrate the better absorption efficiency for both ultra wideband (UWB) and quasi-monochromatic pulses.",
