Extend the analysis to amplitude tapering, parameter selection, and wideband operation

Investigate the impact of amplitude tapering, develop efficient methods for selecting beamfocusing parameters from a physically consistent electromagnetic model, and extend the beamfocusing analysis to wideband operation.

Background

The presented study optimizes Airy-beam parameters by grid search followed by gradient ascent and evaluates a single carrier frequency. It also compares strategies under the adopted phase-focused configurations without developing an efficient general parameter-selection procedure or studying amplitude tapering. The authors explicitly leave all three extensions, including wideband operation, for future work.

References

We also leave to future work the impact of amplitude tapering, efficient methods for selecting beamfocusing parameters from a physically consistent model, and the extension to wideband operation.

Contribution~4: a bounded negative result for a small learned codec, reported under interpretation rules fixed before the model was trained (Section~\ref{sec:learned}), together with a statement of the open problem the classical results imply: capture the coding gain that domain concentration provides without inheriting the artifact signature that destroys detection.
