Abstract The article explores the performance of new silicon photoelectric sensor in partial discharge detection, and compares measured optical pulse with traditional UHF pulse. Through electrical synchronous experiments, analyzes discusses detection performance, working characteristics statistical various sensors, advantages feasibility sensors actual monitoring; In addition, two physical phen...

By employing stimulated Raman backscattering in a plasma, information carried by a laser pulse can be captured in the form of a very slowly propagating plasma wave that persists for a time long compared with the pulse duration. If the plasma is then probed with a short laser pulse, the information stored in the plasma wave can be retrieved in a second scattered electromagnetic wave. The recordi...

We examine the energy exchanged between an electromagnetic pulse and a linear dielectric medium in which it propagates. While group velocity indicates the presence of field energy (the locus of which can move with arbitrary speed), the velocity of energy transport maintains strict luminality. This indicates that the medium treats the leading and trailing portions of the pulse differently. The p...

Analytic expressions for the electromagnetic fields of an ultrashort, tightly focused, linearly polarized laser pulse in vacuum are derived from scalar and vector potentials, using a small parameter which assumes a small bandwidth of the laser pulse. The derived fields are compared with those of the Lax series expansion and the complex-source-point approaches and are shown to be well-behaved an...

We study hydrogenlike target excitation by a traveling electromagnetic pulse. The spatial size of the pulse l5ct (c is the speed of light and t is the pulse duration! is assumed to be comparable or less than the characteristic size of the initially occupied atomic state. When propagating through the atom, the pulse is shown to transform the electron wave function ‘‘slice by slice.’’ These trans...
