This is given to provide a relatively efficient analysis of EM radiation/scattering from an electrically large, planar, periodic, finite arrays with arbitrary boundaries, such as arrays with circular or elliptical boundaries. It is shown that only very few significant DFT terms are sufficient to provide accurate results.EnglishComputational complexityDirectional patterns (antenna)Discrete fourier transformsElectromagnetic wave scatteringMatrix algebraMethod of momentsNumerical methodsRadiationElectromagnetic wave radiationForward backwardAntenna arraysExtension of forward backward method with DFT based acceleration algorithm for the efficient analysis of large periodic arrays with arbitrary boundariesConference Paper10.1109/APS.2003.1220113
