Zamors'ka O. Numerical modeling and optimisation of irradiating systems with semitransparent surfaces

The subjects of research are the resonant and nonresonant irradiating systems with partly transparent surfaces. The aim of the research is constructing and research of mathematical models of these systems and algorithms of optimisation. The variational, iterative, optimisation methods are used. The problems of analysis and synthesis according to the prescribed amplitude directivity pattern of antennas with partly transparent surfaces are posed and solved. Distribution of the surfaces transparency is optimised for conform antennas. Various mathematical models with different accuracy of account of directivity pattern and distribution of the surfaces transparency and their forms, are constructed. The numerical calculations are carried out. The spheres of use are radio engineering, hydroacoustics. The results are partially used.
