Mamedov D. Intellectual synthesis and optimization of microwave filters designs based on the partially filled waveguide-dielectric resonators

Object – a process of computer aided design of microwave filters based on waveguide-dielectric resonators partially filled in H- and E- planes. Aim – to develop a method of intellectual synthesis and optimization of microwave filters designs based on the partially filled WDR, based on artificial intelligence techniques, namely expert systems and strict mathematical models. Subject – the method of intellectual synthesis and optimization of microwave filters designs based on the partially filled WDR. Methods – numerical and analytical methods of the microwave electrodynamics (generalized scattering matrix method, the method of partial areas), artificial intelligence methods (expert systems), modern methods and technologies of programming (OOP, C ++ / CLI). Results – on the basis of an expert system and strict mathematical models a method of synthesis and optimization of microwave filter designs with partially filled waveguide-dielectric resonators in H- and E- planes is developed; mathematical models of this structures of microwave filters based on the generalized scattering matrix method are produced; the process of software Sapphire CAD – intellectual system of microwave filters based on the WDR design development is described; testing of the system and experimental verification of the results are made; a comparison of the quality parameters of the filters based on the WDR with known analogues based on the microstrip resonators is performed. Implementation – in practice of microwave filters design at PJSC "NPP Saturn", in academic activities at NTU "KhPI". Application – computer aided design of microwave devices
