Optimization of microwave devices SIMONE, MARCO PSO cavità risonante optimization ottimizzazione particle swarm ridge waveguide resonant cavity transizione end-launcher Settore ING-INF/02 - Campi Elettromagnetici This thesis deals with the optimization techniques for the improvement of the microwave devices performance. In particular, the technique proposed considers the Particle Swarm Optimization algorithm and applies such an algorithm to different devices. Different techniques are developed to connect the optimization with an electromagnetic analysis tool. In the first method the algorithm has been connected to a numerical technique for the evaluation of the device performance (FDFD). The second technique consists on the integration of the algorithm with a 3D Simulation CAD (HFSS, CST). The microwave devices under test are a ridge waveguide (in different configurations), a resonant cavity, a waveguide impedance transformer and an electromagnetic band gap structure. Both the approaches result to be effective for the purpose even in the event that a constraint between conficting requirements is requested. 2016-03-30 info:eu-repo/semantics/doctoralThesis http://hdl.handle.net/11584/266750 eng numberofpages:115 info:eu-repo/semantics/openAccess Università degli Studi di Cagliari license:Non specificato
