In this paper, two different but complementary techniques developed to generate limited-diffractive electromagnetic (EM) beams and pulses by using radial line slot arrays (RLSA) and leaky-wave (LW) planar devices at microwaves/millimeter waves are presented. In the first part of the paper, two kinds of RLSA Bessel beam launchers are proposed, obtained by implementing an inward cylindrical traveling-wave aperture distribution in the longitudinal and transverse electric field components. Moreover, in the second part, two different LW launchers are presented, namely based on forward and backward leaky-waves.

Abstract
In this paper, two different but complementary techniques developed to generate limited-diffractive electromagnetic (EM) beams and pulses by using radial line slot arrays (RLSA) and leaky-wave (LW) planar devices at microwaves/millimeter waves are presented. In the first part of the paper, two kinds of RLSA Bessel beam launchers are proposed, obtained by implementing an inward cylindrical traveling-wave aperture distribution in the longitudinal and transverse electric field components. Moreover, in the second part, two different LW launchers are presented, namely based on forward and backward leaky-waves.File in questo prodotto:
