Optimization of airgap in a monocentric lens assembly and metasurface based anti-reflecting coating in the long-wave IR regime
Manish Kala, Pawan Singh, Sanjay Kumar Mishra +3
Owing to minimal aberration, larger field-of-view, and high resolution, monocentric lenses are preferred over other imagers in hemispherical image surface scenarios, particularly i…

Evolutions of ring Airy vortex beam and ring Pearcey vortex beam in turbulent atmosphere and a comparative analysis of their channel efficiencies and OAM spectra
Shakti Singh, Sanjay Kumar Mishra, Akhilesh Kumar Mishra
An optical vortex beam propagating through turbulent atmosphere encounters distortions in the wavefront that results in modal scattering. Abruptly autofocussing (AAF) beams with or…
