Dimensional confinement and waveguide effect of Dyakonov surface waves in twisted confined media

Nanophotonics, 2020
We theoretically study Dyakonov surface waveguide modes that propagate along the planar strip interfacial waveguide between two uniaxial dielectrics. We demonstrate that owing to the one-dimensional electromagnetic confinement, Dyakonov surface waveguide

Left-Handed Surface Waves in a Photonic Structure

, 2002
It is demonstrated that an isotropic left-handed medium can be constructed as a photonic structure consisting of two dielectric materials, one with positive and another with negative dielectric permittivities epsilon.

Surface waves in deformed Bell materials [PDF]

, 2012
Small amplitude inhomogeneous plane waves are studied as they propagate on the free surface of a predeformed semi-infinite body made of Bell constrained material. The predeformation corresponds to a finite static pure homogeneous strain. The surface wave

Complex dynamics in nonlinear small time-delayed optoelectronic oscillator and application in fast reservoir computing and pulse generation

Scientific Reports
We investigated a time-delayed optoelectronic oscillator (OEO) that displays a wide range of complex dynamic behavior under small time delay. The phase-space trajectory distributions in different dynamic regimes were compared which brings a new ...

Modulation of Surface Elastic Waves and Surface Acoustic Waves by Acoustic–Elastic Metamaterials

Crystals
Metamaterials enable the modulation of elastic waves or acoustic waves in unprecedented ways and have a wide range of potential applications. This paper achieves the simultaneous manipulation of surface elastic waves (SEWs) and surface acoustic waves ...

Resonant Scattering of Surface Plasmon Polaritons by Dressed Quantum Dots

, 2014
The resonant scattering of surface plasmon-polariton waves by embedded semiconductor quantum dots above the dielectric/metal interface is explored in the strong-coupling regime.

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Relocation of Light and Moderate‐Magnitude (M4–6) Seismicity Along the Central Mid‐Atlantic

Geochemistry, Geophysics, Geosystems, 2018
We estimate precise relative epicentroid locations of earthquakes along the Mid‐Atlantic Ridge (MAR) between 12°N and 19°N using intermediate‐period Rayleigh and Love wave cross‐correlation measurements.

Nonlinear ring waves in a two-layer fluid [PDF]

, 2016
Surface and interfacial weakly-nonlinear ring waves in a two-layer fluid are modelled numerically, within the framework of the recently derived 2+1-dimensional cKdV-type equation.
