Generation of Non-Diffractive Bessel Beams for Near-Field Links Applications Using Meta-Axicons

Résumé

This contribution explores the generation of a linearly-polarized Bessel-Gauss beam generated by a fully dielectric metasurface axicon (meta-axicon) illuminated with a Gaussian beam. It is shown that this Bessel launcher generates a beam with similar characteristics as compared to the one that would be radiated by an ideal aperture. A theoretical model is presented, which allows to estimate the wireless power transfer efficiency (WPTE) of a system composed of two identical such launchers. We investigate the radiated fields, both in the direct and spectral domains obtained with the model and full-wave simulations.
