Based on contemporary research, it formulates multi-objective design tasks, highlights related challenges in the context of antenna design, and discusses solution approaches. Specific focus is on providing methodologies for handling computationally expensive simulation models of antenna structures in the sense of their multi-objective optimization. Also given is a summary of recent developments in antenna design optimization using variable-fidelity simulation models. Numerous examples of real-world antenna design problems are provided along with discussions and recommendations for the readers interested in applying the considered methods in their design work. Written with researchers and students in mind, topics covered can also be applied across a broad spectrum of aeronautical, mechanical, electrical, biomedical and civil engineering. It is of particular interest to those dealing with optimization, computationally expensive design tasks and simulation-driven design."--Publisher's website.Antennas (Electronics)Simulation methodsAntennas (Electronics)Mathematical modelsAntennas (Electronics)Design and constructionMultiple criteria decision makingAntennas (Electronics)Simulation methods.Antennas (Electronics)Mathematical models.Antennas (Electronics)Design and construction.Multiple criteria decision making.621.382/4Koziel Slawomir721636Bekasiewicz AdrianMiAaPQMiAaPQMiAaPQBOOK9910155157503321Multi-objective design of antennas using surrogate models2586736UNINA05278nam 2200745Ia 450 991101954440332120200520144314.097866102727169781280272714128027271697804703467230470346728978047122110404712211049780471463832047146383397816011938721601193874(CKB)111087027107986(EBL)221339(OCoLC)475926535(SSID)ssj0000378895(PQKBManifestationID)11267003(PQKBTitleCode)TC0000378895(PQKBWorkID)10355935(PQKB)10608566(MiAaPQ)EBC221339(Perlego)2765215(EXLCZ)9911108702710798620020410d2002 uy 0engur|n|---|||||txtccrOptimum array processing /Harry L.
