We consider an one-dimensional problem of propagation of a short light pulse in a medium with Lorentz contour of the spectral gain line. Simple approximate formulas for the spatial distribution of the field at any time are obtained. It is shown that

This paper considers the question of superluminal (or negative) group velocities of signals in dispersive media, as well as negative group delay times of signals passing through linear filters. It is shown that information can be transmitted only wit

A pulse with rectangular envelope propagation, in which carrier frequency is close to the medium spectral absorption line’s one frequency, is considered. It is shown that when the signal carrier frequency is shifted relative to the spectral line ce

Background One of the sources of environmental pollution is surface wastewater, as well as other liquid-phase pollution (for example, oil products) from the railway right-of-way. Since these pollutants entering the environment from railway transport

The propagation of a light pulse through a layer of a substance with population inversion and, correspondingly, with an anomalous dispersion in the transparency range is considered. It is shown that, when the wave packet approaches the layer of the s

We consider the time dependence of a total signal from two point acoustic sources emitting similar quasimonochromatic signals (two-beam interference of quasimonochromatic waves). It is shown that the time dependence of the envelope function of the to

The 1D problem related to the distortion of the rising edge of a carrier-free signal, which arise abruptly at the starting point, is examined. It is demonstrated that, in propagation through an arbitrary (including, absorbing) medium, the signal’s

An approximate analog of the Kramers-Kronig relationships for an isolated spectral line is proposed. Expressions are obtained for the real part of the dielectric susceptibility of a substance near a spectral line for collisional, Doppler, and time-of

Impressions of the peltaspemous female fructifications from the Novy Kuvak locality (the Kazanian of the Samara Region, Russia) are described as Peltaspermopsis nebritovii sp. nov. They represent racemose fertile shoots about 7 cm in length and 3 cm
