Demystifying Self-healing Property of Accelerating Beams for Obstacles Circumvention in Communication Applications

This paper deals with the application of self-accelerating beams for obstacle circumvention in communication applications. Particularly, although recent research works have proposed to take advantage of the self-healing property of self-accelerating beams like the Airy beam to circumvent obstacles and enable data transmission in non-line-of-sight (non-LOS) scenarios, the analysis presented in this paper shows that this is not a viable approach, at least when the transmission aperture dimension is comparable or smaller than that of the obstacle. Ray-optics interpretation, equivalent point source propagation models which take into account the presence of obstacles of different sizes, and full-electromagnetic wave simulation results will be provided to confirm this fact.
