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.

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.

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 ...

Recent Developments of Femtosecond Laser Direct Writing for Meta-Optics
Nanomaterials, 2023 Micro-optics based on the artificial adjustment of physical dimensions, such as the phase, polarization, and wavelength of light, constitute the basis of contemporary information optoelectronic technology. As the main means of optical integration, it has

Supporting quadric method for collimated beams [PDF]
Компьютерная оптика, 2021 We consider the problem of calculating a refractive element with two surfaces, forming a flat front and a given distribution of illumination. The supporting quadrics method is formulated for calculating a given optical element and it is shown that this ...

Geometrically robust linear optics from non-Abelian geometric phases
Physical Review Research, 2022 We construct a unified operator framework for quantum holonomies generated from bosonic systems. For a system whose Hamiltonian is bilinear in the creation and annihilation operators, we find a holonomy group determined only by a set of selected ...

Level of Students Conceptual Understanding and Resource Theory View: Geometric Optics
International Journal of Education and Teaching Zone, 2022 This study aims to identify the level of understanding (LoU) and resources that students activate. This is a descriptive study. The study used a survey method by distributing ten multiple-choice questions. The focus of the study is geometric optics.

Semilinear geometric optics with boundary amplification [PDF]
, 2012 We study weakly stable semilinear hyperbolic boundary value problems with highly oscillatory data. Here weak stability means that exponentially growing modes are absent, but the so-called uniform Lopatinskii condition fails at some boundary frequency ...
