Abstract
Localized beams and pulses, such as Bessel beams and X-waves exhibit remarkable focusing features in the near-field region. We discuss here novel figures of merit for evaluating spatial resolutions of these limited-diffractive, limited-dispersive solutions of wave equation. Specific attention is devoted to the design of planar millimeter-wave launchers, thoroughly addressing the radial wavenumber dispersion that notably affects the propagation of such pulses. The presented results can help in the application-oriented design of X-wave launchers in the microwave and the millimeter-wave range.File in questo prodotto:
