Electrical Parameters of a Laser Beam Channel in the Atmosphere. II
摘要： Results of measurements of the conductivity and electric field strength in the laser radiation propagation channel and near it are presented. An experimental setup and measurement scheme are described. The data have been obtained in the prebreakdown regime. The dependences of the laser-induced field strength on the laser radiation power and the optical characteristics of the propagation channel are investigated. The feasibility of ionization channel diagnostics using the electro-optical effects in the atmosphere is shown.

[Institution of Engineering and Technology 12th European Conference on Antennas and Propagation (EuCAP 2018) - London, UK (9-13 April 2018)] 12th European Conference on Antennas and Propagation (EuCAP 2018) - Polarimetric wideband directional channel measurement and analysis for outdoor small cell scenarios at 32 GHz and 39 GHz
摘要： Wideband millimeter-wave (mmWave) directional propagation measurements were conducted in the 32 GHz and 39 GHz bands in outdoor line-of-sight (LoS) small cell scenarios. The measurement provides spatial and temporal statistics that will be useful for small-cell outdoor wireless networks for future mmWave bands. Measurements were performed at two outdoor environments and repeated for all polarization combinations. Measurement results show little spread in the angular and delay domains for the LoS scenario. Moreover root-mean-squared (RMS) delay spread at different polarizations show small difference which can be due to specific scatterers in the channel.
