Investigation of the coherent combination of a 19-fiber laser beam characteristics to achieve a multi tens of kW at a distance of 10 km

In this paper, we used a coherent beam combination to design a 50 kW high power laser beam for energy applications.Because of the strong environmental turbulence, degrade the coherent beam combination advantages, low turbulence level is considered.Combining elements are composed of 19 polarized single mode 3 borstlist självhäftande kW high power

Low-Profile Implementation of U-Shaped Power Quasi-Isotropic Antennas for Intra-Vehicle Wireless Communications

Intra-vehicle gotrax handlebar wireless communication applications, e.g.the wireless sensor network, are in need of antennas with uniformly radiated power for signal transmitting and receiving with their randomly distributed neighboring targets.This demand can be met with power quasi-isotropic antennas with low angular gain variation (GV).In this p
