Abstract
In this paper we illustrate how the localization of the stationary two-dimensional solution of the propagation equation strongly depends on the features of its spatio-temporal spectral bandwidth. We especially investigate the role of the ultra-broad temporal support and of the spatial bandwidth of the spectrum on the high localization in one spatial dimension of \&\#x0201D;Bessel-like\&\#x0201D; or \&\#x0201D;blade-like\&\#x0201D; beams, quasi-stationarily propagating in normally dispersive materials, and potentially interesting for microfabrication applications.
