Документ Evolutionary design of seven-tier LM-mode filters optimized with original knowledge-based cad system(НТУ "ХПИ", 2014) Yushchenko, A. G.; Mamedov, D. B.The evolutionary strategy of multi-tier WDR-filters with LM-modes, optimized with original knowledge-based CAD system designing is proposed and tested. Main point of the strategy is to solve the problem of synthesis and optimization of the seven- (or more) tiered filter through the gradual complication of the simplest one-tiered design, which corresponds to the evolutionary principle of gradual cost function complication. The efficiency of the strategy is confirmed by the designing of three to five and seven-tier millimeter filters, which are intended for the next generation of millimeter wave-band wireless systems and conform to the latest standards like ECMA-387, Wireless HD, IEEE 802.15.3c and IEEE 802.11ad.Документ Intellectual CAD of mm waves WDR filters with increased stop band attenuation(НТУ "ХПІ", 2012) Yushchenko, A. G.; Mamedov, D. B.Physical principles of the original intellectual CAD development for three-tier WDR filters with increased stop band attenuation are presented in the article. The electrodynamic parameters of the partly filled resonators with quasi-H101 and quasi- H102 eigenmodes, which influencing on their frequency separation are analysed. The results of filters designing, proper to the recent standards ECMA-387, WirelessHD, IEEE 802.15.3c, IEEE 802.11ad, are presentedДокумент Ultra-Wideband Five-Tier LM-mode Filters Optimized with knowledge-based CAD system(НТУ "ХПІ", 2013) Yushchenko, A. G.; Mamedov, D. B.An original knowledge-based CAD system for step-by-step automated development offive-tier filters base don wave guide-dielectric resonators with the lowest LM-modes has been proposed. The basic idea of the system created consists in physical analysis of signals passing through the filter, which is performed on the basis of a known solution for electrodynamic problem of scattering of fundamental electromagnetic waves in a multi-tier structure. Regularities in formation of the filter ultra-wide bandwidths and formalized them in the form of production rules for the system were discovered. A comparative analysis of frequency responses for three- and five-tier UWB filters, optimized with the system has been also provided. The designed filters are intended for the next generation of millimeter waveband wireless systems and conform to the latest standards like ECMA-387, WirelessHD, IEEE 802.15.3c and IEEE 802.11ad.
