Quasinormal modes in two-photon autocorrelation and the geometric-optics approximation [PDF]
The European Physical Journal C, 2021 In this work, we study the black hole light echoes in terms of the two-photon autocorrelation and explore their connection with the quasinormal modes. It is shown that the above time-domain phenomenon can be analyzed by utilizing the well-known frequency-

Kerr-spacetime geometric optics for vortex beams [PDF]
Physical Review A, 2021 We apply the analogy between gravitational fields and optical media in the general relativistic geometric optics framework to describe how light can acquire orbital angular momentum (OAM) when it traverses the gravitational field of a massive rotating ...

Single-scattering properties of ellipsoidal dust aerosols constrained by measured dust shape distributions [PDF]
Atmospheric Chemistry and Physics, 2023 Most global aerosol models approximate dust as spherical particles, whereas most remote sensing retrieval algorithms approximate dust as spheroidal particles with a shape distribution that conflicts with measurements.

Toward Arbitrary Spin‐Orbit Flat Optics Via Structured Geometric Phase Gratings [PDF]
Laser & Photonics Reviews, 2023 Reciprocal spin‐orbit coupling (SOC) via geometric phase with flat optics provides a promising platform for shaping and controlling paraxial structured light.

Физика волновых процессов и радиотехнические системы, 2023 Calculation of the electromagnetic field exited by a charged particle flying close to dielectric object is one of the important problems of charged particle radiation theory. In some cases, geometric optics area is preferable for calculations.

Gravitational Spin Hall Effect in Curves Spacetimes
Physical Sciences Forum, 2023 Geometric optics approximation sufficiently describes the effects in the near-earth environment, and Faraday rotation is purely a reference frame effect in this limit. A simple encoding procedure could mitigate the Faraday phase error.

Gravitational lensing beyond geometric optics: I. Formalism and observables [PDF]
General Relativity and Gravitation, 2019 The laws of geometric optics and their corrections are derived for scalar, electromagnetic, and gravitational waves propagating in generic curved spacetimes. Local peeling-type results are obtained, where different components of high-frequency fields are

Recent Advances in Planar Optics-Based Glasses-Free 3D Displays
Frontiers in Nanotechnology, 2022 Glasses-free three-dimensional (3D) displays are one of the technologies that will redefine human-computer interfaces. However, many geometric optics-based 3D displays suffer from a limited field of view (FOV), severe resolution degradation, and visual ...

Geometric optics in the presence of axionlike particles in curved spacetime [PDF]
, 2020 We present a concise derivation of geometric optics in the presence of axionic fields in a curved space-time. Whenever light can be described via geometric optics (the eikonal approximation), the only difference to the situation without axionic field is ...
