The research object: the electromagnetic fields, scattered on the flat screens of finite thickness with coaxial-sector apertures. The purpose is development of the electrodynamic model and efficient numerical algorithm for calculating the characteristics of electromagnetic fields scattered on the flat metal screens of finite thickness with coaxial-sector apertures, with no limit on the geometric parameters of the structures. Research methods: the method of partial domains and the operator method. New theoretical and practical results: the physical results in the diffraction of electromagnetic waves on metal structures with coaxial-sector apertures allow the use of the proposed structure as frequency-selective surfaces and polarization converters of electromagnetic waves; the application of the proposed structures in various microwave devices will improve their performance; the observed effect of nonspecular reflection of electromagnetic waves from the array of the shorted coaxial-sector waveguides can be used for designing various devices, such as spatial filters or resonators open multimirrors sparse spectrum. Application extent: the results are planned to be applied. Application field: radiophysics and electronics.
