Analytic transfer-matrix calculations and full-wave time-domain simulations are deployed to calculate, both in the frequency and in the time domain, the losses or gain experienced by complex-wave-vector and complex-frequency modes. We find excellent agreement between five distinct sets of results, showing that the use of evanescent pumping (gain) can compensate the losses in the NRI slow- and stopped-light regimes. © 2011 American Physical Society.</style></abstract><notes><style face="normal" font="default" size="100%">cited By 19</style></notes></record></records></xml>
