Selective avoidance of multiple line-of-sight obstacles at 130~m using locally bending space-time wave packets
Layton A. Hall, Murat Yessenov, Isabelle Lebron +1
The paper demonstrates pulsed space‑time wave packets whose spatiotemporal spectrum is engineered to locally bend around one or multiple line‑of‑sight obstacles, allowing the beam…
Avoiding a line-of-sight obstacle via deep sub-Rayleigh shadow-projection utilizing space-time wave packets
Layton A. Hall, Bryan L. Turo, Ayman F. Abouraddy
A challenge in optics, which is shared by other sources of radiation, is to direct a coherent beam to impinge on a target behind an obstacle intervening in the line-of-sight (LoS).…
Exact Self-Imaging with Arbitrary Revival Spacings
Layton A. Hall, Samuel Alperin
Self-imaging represents a core hallmark of paraxial wave evolution; yet, across its many realizations and generalizations over the past two centuries, the uniformity of recurrence…
Passive Cross-Basis Mode Transitions Along a Single Freely Propagating Bessel Beam
Henry P. Evans, Layton A. Hall
The transverse modal identity of a freely propagating optical beam is ordinarily fixed at the point of generation. We show that the conical angular spectrum of a Bessel beam establ…
