Tsaliev T. Aperture type antennas with a discrete working surface (bases of the theory and the diffraction analysis

Object of research is the phenomena of diffraction of a monochromatic electromagnetic field on ideally conducting or impedance discrete surfaces. The purpose of research consists in development electro dynamically correct mathematical models of antennas with a discrete surface, methods of the analysis of their properties, improvement of the form of discrete surfaces on the basis of which solve problems of creation of family low profile reflectors and lenses with a discrete working surface. The diffraction analysis method of characteristics with ideally conducting discrete surface antenna elements consists of two series stage of numerical decision of the diffraction task. The numerical decision of two-dimensional diffraction tasks is realized and the analysis of properties of discrete surfaces, which are elements of the aperture antennas and focusing devices, is carried out.
