Boosted Kerr Black Hole in the Presence of Plasma
Proceedings, 2019 In this work, we obtain the deflection angle for a boosted Kerr black hole in the weak field approximation using the optics in a curved spacetime developed by J. L. Synge in 1960.

Singular random matrix decompositions: distributions. [PDF]
, 2002 Assuming that Y has a singular matrix variate elliptically contoured distribution with respect to the Hausdorff measure, the distributions of several matrices associated to QR, modified QR, SV and Polar decompositions of matrix Y are determined, for ...

A Riccati equation approach to construct new dispersive solitons to the Kaup-Newell equation [PDF]
Memoirs of the Scientific Sections of the Romanian Academy, 2020 The present paper examines analytically the Kaup-Newell equation, an important class of nonlinear Schrodinger equations with lots of applications in optical fibers. The Riccati equation approach is employed for the present study. The method is one of the

Rotating vortex imaging implemented by a quantized spiral phase modulation [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 We demonstrate both theoretically and experimentally that a spiral mask with a finite number of discrete phase levels allows a defocusing induced rotation of the point spread function in the vortex imaging.

Compound Vector Light Generator Based on a Metasurface
Photonics, 2021 In view of wide applications of vector light with a non-uniform polarization state, a compound vector light generator is proposed to generate compound vector light. One compound vector light contains two or more non-uniform polarization modes and several

Partial transmutation of singularities in optical instruments [PDF]
Journal of Optics, 2011 Some interesting optical instruments such as the Eaton lens and the Invisible Sphere require singularities of the refractive index for their implementation. We show how to transmute those singularities into harmless topological defects in anisotropic media without the need for anomalous material properties.

Creating and Controlling Polarization Singularities in Plasmonic Fields
Photonics, 2015 Nanoscale light fields near nanoplasmonic objects can be highly structured and can contain highly-subwavelength features. Here, we present the results of our search for the simplest plasmonic system that contains, and can be used to control, the smallest

Generation of hexagonal close-packed ring-shaped structures using an optical vortex
Nanophotonics, 2021 An optical vortex possesses a ring-shaped spatial profile and orbital angular momentum (OAM) owing to its helical wavefront. This form of structured light has garnered significant attention in recent years, and it has enabled new investigations in ...

Hybridization of singular plasmons via transformation optics [PDF]
Proceedings of the National Academy of Sciences, 2019 Significance Surface plasmons, which are optical resonances supported by metallic nanostructures, are extremely useful for manipulating light on the nanoscale. However, designing novel plasmonic devices becomes quite challenging when the desired spectral response pattern is highly complex.
