Bessel beams (BBs) can be generated at microwave frequencies by means of compact,
planar devices based on Fabry–Perot cavity leaky-wave resonators. Most designs are based …

In this communication, we present a theoretical analysis, design, and fabrication of a limited-
diffractive planar Bessel beam launcher, that exhibits a zeroth-order Bessel profile in the …

Resonant Bessel-beam launchers are low-cost, planar, miniaturized devices capable of
focusing electromagnetic radiation in a very efficient way in various frequency ranges, with …

This chapter illustrates the capabilities of non-diffractive Bessel beams for near-field
focusing. After a brief introduction of the non-diffractive phenomenon and its origin, the …

Transverse-electric (TE) polarized Bessel-beam launchers working at millimeter-wave
frequencies are theoretically described, simulated, realized, and experimentally validated. A …

Localized waves, ie, the wide class of limited-diffraction, limited-dispersion solutions to the
wave equation are generally characterized by real wave numbers. We consider the role …

In this letter, we propose a design of a dual circular-polarized antenna for L-band
applications (1.1-1.6 GHz). The designed antenna has been developed by considering …

Ces dernières années, la thématique des métasurfaces est devenue un sujet de recherche
en pleine expansion dans plusieurs domaines de l'ingénierie et de la physique appliquée …

The transverse linearly polarized beam can maintain its polarization when reflected, which is
important for a detection system. Most of the existing planar Bessel beam generators are …

In this letter, the scattering of a nondiffractive Bessel beam (BB) incident field by a perfect
electric conducting circular cylinder is investigated and compared with the standard …
