چکیده انگلیسی
In recent years, the problem of the production of localized waves has been analyzed in various ways, from both a theoretical and a practical point of view. We present here a way in which to construct a suitable experimental setup, so as to obtain highly localized energy. On the basis of a vectorial treatment already studied for a specific source (namely, a ring-shaped aperture over a metallic screen), we evaluate the amount of energy supplied by a single Bessel beam. Then, by analyzing the geometric characteristics of the experimental setup, we can establish the position of further rings, so as to increase the localized energy to a maximum.
