Investigate additional motivations for elaborate beamfocusing techniques

Investigate whether elaborate beamfocusing techniques such as Airy beams provide practical benefits for self-healing or for enabling constant-output-power operation through phase-only control.

Background

The paper concludes that Airy-beam-based beamfocusing is not worthwhile for the considered occlusion scenarios because a line-of-sight strategy is sufficient in partially occluded regions and a closed-form optimal strategy is available when a physically consistent model is used. It nevertheless notes that elaborate beamfocusing techniques could be attractive for purposes not evaluated in the paper, specifically self-healing and operation of power amplifiers at constant output power through phase-only control.

References

We conclude by noting that elaborate beamfocusing techniques, such as Airy beams, may nonetheless be attractive for other reasons, such as self-healing or the fact that purely controlling the phase allows the PAs to operate at constant output power; we leave an investigation of such aspects for future work.

Further open questions include the analysis of scenarios with obstacles of different shapes and positions, as well as a comparison with other beam types, such as Gaussian, Bessel, and nonparaxial accelerating beams of the Mathieu and Weber type.
