1) Investigations of HF data transmission channels in the territory of the Republic of Kazakhstan have been carried out. The review of existing communication channels and their characteristics is carried out. It was revealed that high reliability of HF data transmission channels can be achieved by improving the operation of existing communication networks, improving their technical condition, and also their subsequent modernization and smooth transition to the development and implementation of new data transmission channels. Prospects for their use are given. The results of the work were presented at international conferences and seminars in the Republic of Kazakhstan.
2) Numerical investigation and simulation of the process of locking the Schottky field-effect transistor with account taken of the edge effects at the drain end of the gates, caused by the appearance of regions with a high concentration of the electric field strength, are carried out. The physical and mathematical formulation of the problem of the distribution of the electric field strength and electron concentration in an isotropic conducting medium is presented. Taking into account the above assumptions, this problem was solved in the two-dimensional case, which allows one to take into account the end-effects arising in the process. The methodology, algorithm and calculation program are developed. Test calculations and numerical studies are performed depending on the determining characteristics of the Schottky field effect transistor: the potential difference at the gate, source and drain. The results of numerical studies and their analysis are presented. It is shown that the change in the conductivity of the channel, depending on the applied voltage on the gate, is nonlinear, and is caused by edge effects. The value of the gate potentials and the effect on the channel capacity of the duration of the applied voltage on the gate are determined. It is also shown that for V-type devices, it is necessary to expect a significant influence of edge effects on the throughput predetermined by the location of the main flow near the junction of the electrode and insulator. The results of the work are presented at international conferences and published in Russian and foreign publications, successfully defended the master's thesis.
