Revisiting Tide‐Induced Near‐Field Mixing in the Abyssal Ocean
Geophysical Research LettersVertical two‐dimensional numerical experiments incorporating Garrett‐Munk (GM) internal waves are conducted to investigate tide‐induced near‐field mixing over a finite‐amplitude sinusoidal seafloor, conventionally attributed to the breaking of high ...

Polarization Stable Triband Thin Square-Shaped Metamaterial Absorber
International Journal of Antennas and Propagation, 2023 An efficient triband metamaterial absorber is presented for X- and K-band applications. The unit cell is of simple shape. The absorber is fabricated on a thin polyamide, which makes it flexible. The parameters of the designed absorber are optimized.

Bound States in the Continuum and Fano Resonances in the Dirac Cone Spectrum
, 2019 We consider light scattering by two dimensional arrays of high-index dielectric spheres arranged into the triangular lattice. It is demonstrated that in the case a triple degeneracy of resonant leaky modes in the Gamma-point the scattering spectra ...

Engineering Topological Phases with a Traveling‐Wave Spacetime Modulation
Laser &Photonics Reviews, EarlyView.Time‐varying systems have garnered considerable attention due to their unique potential in manipulating electromagnetic waves. Here, a novel class of topological spacetime crystals with a traveling‐wave modulation is introduced. By manipulating material anisotropy, one can engineer light angular momentum and non‐trivial topological phases characterized

Inductive twin-strip gratings in incident TE waves
Electronics Letters, 1983 The inductive sides of square loops, or the inductive end caps of the Jerusalem cross, are regarded as segments of a regular strip grating, in order to devise equivalent-circuit models of frequency surfaces. This approximation involves errors, depending on frequency, angle of incidence and the choice of the grating.

Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials
Laser &Photonics Reviews, EarlyView.This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...
