On the project

Řešený projekt reaguje na přesun rádiové komunikace do stále vyšších kmitočtových pásem. V jeho rámci jsou rozvíjeny tradiční i netradiční metody numerické analýzy speciálních mikrovlnných obvodů a antén a jsou vypracovávány nové postupy pro jejich návrh a optimalizaci, které využívají umělých neuronových sítí a genetických algoritmů. První rok řešení byl přitom zaměřen především na problematiku numerické analýzy, v druhém a třetím roce řešení projektu je plánován rozvoj optimalizačních metod a experimentální ověření výsledků.

Description in English
The project deals with the development of effective numerical methods of analysis, optimization and design of microand millimeter-wave structures (antennas, microstrip and waveguide circuits). Analysis. Quick and accurate algorithms for computing parameters of microwave antennas, special microstrip circuits and three-dimensional waveguide structures are the main goal of this part of the project. Algorithms will be based on standard methods (method of moments, method of conformal mapping, finite elementmethod). High speed and accuracy will be achieved by combining methods, by translating problems from space to frequency domain and by application of the conformal mapping to special microstrip structures. Optimization and design come from the rough mat hematical model of designed or optimized structure. During the optimization process, physical parameters of the model are consecutively changed so as the technical parameters could meat their desired values. High effectiveness of the optimization process
