Evaluating the Bessel Characteristics of a Curved Beam in Near- and Far-Field Regions

This paper presents a curved beam generated by a metasurface operating in the ITS-G5 frequency band, categorized as a hybrid Bessel beam. The beam is designed to improve communication in complex metallic environments, such as toll stations. Therefore, evaluating its properties is essential to confirm its classification as a non-diffractive beam, known for resistance to diffraction and self-healing capabilities, both of which are demonstrated here. Near- and far-field analyses confirm the ability of the metasurface to efficiently bend electromagnetic waves, providing enhanced connectivity solutions for automated vehicle communication systems in challenging environments.
