On the relation between the propagation constant of Bloch surface waves and the thickness of the upper layer of a photonic crystal [PDF]
Компьютерная оптика, 2018 We consider the derivation of a dispersion relation of Bloch surface waves supported by interfaces between a semi-infinite one-dimensional photonic crystal and a homogeneous medium.

Stability Analysis for an Interface with a Continuous Internal Structure
Fluids, 2021 A general method for solving a linear stability problem of an interface with a continuous internal structure is described. Such interfaces or fronts are commonly found in various branches of physics, such as combustion and plasma physics.

Dispersion relations in κ-noncommutative cosmology [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 Abstract We study noncommutative deformations of the wave equation in curved backgrounds and discuss the modification of the dispersion relations due to noncommutativity combined with curvature of spacetime. Our noncommutative differential geometry approach is based on Drinfeld twist deformation, and can be implemented for any twist and

Radiative Corrections to Semileptonic Beta Decays: Progress and Challenges
Particles, 2021 We review some recent progress in the theory of electroweak radiative corrections in semileptonic decay processes. The resurrection of the so-called Sirlin’s representation based on current algebra relations permits a clear separation between the ...

Controlling Refraction Using Sub-Wavelength Resonators
Applied Sciences, 2018 We construct metamaterials from sub-wavelength nonmagnetic resonators and consider the refraction of incoming signals traveling from free space into the metamaterial.

Wave Equation Numerical Simulation and RTM With Mixed Staggered-Grid Finite-Difference Schemes
Frontiers in Earth Science, 2022 For the conventional staggered-grid finite-difference scheme (C-SFD), although the spatial finite-difference (FD) operator can reach 2Mth-order accuracy, the FD discrete wave equation is the only second-order accuracy, leading to low modeling accuracy ...
