On the question of optimization of mutual influence of channels for receiving of information and channels of antenna self-direction operating on the basic information signal

At use of mirror aerials mutual influence of channels of reception of the information and channels of self-direction can be shown through mutual communication of the irradiators, taking place in a near zone of each one, and through elements of microwave devices realizing total-differentiated processing, etc. In the work the optimization of the circuit is considered in view of minimization of mutual influence of channels of reception of the information and the channels of self-direction operating on the basic information signal

Linear phased antenna array with low level of side radiation

Technical solution of design of linear phased antenna array consisting of speaking-trumpet radiating elements with controlled phase-rotators and uniform amplitude distribution along the array is proposed. Low level of side radiation is provided by special shift of phase-rotators phases, which does not require any changes in grid design

Transportation of cold plasma jet in multiple-mirror magnetic field

New experimental results on magnetic compression and transport of low-temperature arc plasma are presented. In the experiments, the transport efficiency of the plasma stream in a multiple-mirror configuration was compared with the same in a uniform solenoidal field. The magnetic compression ratio of the plasma stream varied from 5 to 60 at the initial diameter of 5 cm. As the result, the plasma with (1 – 4)×1020 m-3 density at the axis was obtained at ∼3 m distance from the plasma source. Theory predicted that a multiple-mirror magnetic field should not significantly decelerate and weaken collisional plasma. The experiment confirmed this prediction. In the presented work, we simulated the baseline scenario of GOL-NB filling by cold start plasma
