Approximation by Quad Meshes in Laguerre Geometry
We study the analogs of planar-quadrilateral meshes in Laguerre sphere geometry and the approximation of smooth surfaces by them. These new Laguerre meshes can be viewed as watertight surfaces that are formed by planar quadrilaterals (corresponding to the vertices of a mesh), strips of right circular cones (representing the edges) and spherical faces ...

One Metasurface for Four‐Channel Terahertz Wavefront Manipulation Based on Vanadium Dioxide
Advanced Physics Research, Volume 5, Issue 4, April 2026.This article presents a thermally reconfigurable metasurface utilizing vanadium dioxide (VO2) to dynamically switch between four independent wavefront‐manipulation channels. By synergizing geometric and propagation phases, the platform enables spin‐decoding for circularly polarized waves and polarization multiplexing for linearly polarized waves ...

Generation of Optical Quasiparticles with Spin–Orbit Conversion in a Single Q‐Plate
Laser &Photonics Reviews, Volume 20, Issue 7, 6 April 2026.Spin‐Orbit conversion approach with a q‐plate for generating optical quasiparticles. ABSTRACT In this work, we detail a novel approach which can be used for the generation of optical quasiparticles. This process leverages both spin‐orbit conversion control with wavelength de‐tuning in a commercially available q‐plate.

Fractional Orbital Angular Momentum Sorting Using Wind Spiral Transformation
Nanophotonics, Volume 15, Issue 8, 24 April 2026.A wind‐spiral coordinate transformation enables mode sorting of fractional‐order orbital angular momentum (OAM) states, overcoming the limited channel count of conventional integer only sorters. Fractional OAM is mapped into a controlled superposition of integer modes, producing distinctive multi‐peak signatures for discrimination.

4-dimensional elation Laguerre planes with 9-dimensional automorphism groups.
Topological Laguerre planes are circle geometries with one parallelism relation and a topology on the point set and circle set such that the geometric operations of joining, touching, parallel projection and intersection are continuous.

Classifying pseudo-ovals, translation generalized quadrangles, and elation Laguerre planes of small order [PDF]
We provide classification results for translation generalized quadrangles of order less than or equal to 64, and hence, for all incidence geometries related to them.
