Paper Abstract

We discuss an appearance of the false absorption frequencies which are caused by process of the frequency conversion at action of the broadband THz pulse. The physical reason of their occurrence is discussed. A way for definition of the false absorption frequencies is proposed. A few experiments, which suppose the existence of such frequencies, are presented. However, we propose using of the up-conversion of THz frequencies for the detection and identification of substances.
