Singular graphene metasurfaces
EPJ Applied Metamaterials, 2019 The spatial tunability of the electron density in graphene enables the dynamic engineering of metasurfaces in the form of conductivity gratings, which can bridge the momentum gap between incident radiation and surface plasmons.

Generalized Antiorthotomics of (n, m)-Cusp Curves
MathematicsIn optics, light rays emitted from a light source form a wavefront (orthotomic) upon reflection by a mirror. The mirror is referred to as an antiorthotomic of the orthotomic.

Measure Data Problems for a Class of Elliptic Equations with Mixed Absorption-Reaction
Advanced Nonlinear Studies, 2021 In the present paper, we study the existence of nonnegative solutions to the Dirichlet problem ℒp,qMu:=-Δu+up-M|∇u|q=μ{{\mathcal{L}}^{{M}}_{p,q}u:=-\Delta u+u^{p}-M|\nabla u|^{q}=\mu} in a domain Ω⊂ℝN{\Omega\subset\mathbb{R}^{N}} where μ is a ...

Singularities of Type-Q ABS Equations
Symmetry, Integrability and Geometry: Methods and Applications, 2011 The type-Q equations lie on the top level of the hierarchy introduced by Adler, Bobenko and Suris (ABS) in their classification of discrete counterparts of KdV-type integrable partial differential equations.

Singularities in the flying electromagnetic doughnuts
Nanophotonics, 2019 Flying doughnuts (FDs) are exact propagating solutions of Maxwell equations in the form of single-cycle, space-time non-separable toroidal pulses. Here we review their properties and reveal the existence of a complex and robust fine topological structure.
