Mochurad L. Mathematical modeling of the electronic optic systems taking into account the symmetry of the boundary surfaces

The modern scientific task of the electrostatic field calculations in the modeling process of the electron-optical systems with the symmetry appeared in geometry of the surfaces- electrodes is solved in the thesis. This solution is realized via the construction and improvement of the numerical modeling methods in the case of the complicated electrostatic fields. These methods are based on the integral equations method connected with the group theory, domain decomposition method and apparatus of Green function. The proposed system of methods allowed us to use the main computer memory more effectively, diminishing it by squared order of group while constructing every system of linear algebraic equations which approximate the corresponding integral equations. Thus, the type of tasks which assumes a numeral modelling with the use of the method of boundary integral equations is broaden. Also, pre-conditions for parallelization of the solving process in general are created.
