Temperature–Mediated Transition From Dyakonov Surface Waves to Surface–Plasmon–Polariton Waves

open access: yesIEEE Photonics Journal, 2016
The propagation of electromagnetic surface waves, guided by the planar interface of a temperature-sensitive isotropic material and a temperature-insensitive uniaxial material, each characterized by a relative permittivity dyadic, was investigated ...

Optimization Design of Surface Wave Electromagnetic Acoustic Transducers Based on Simulation Analysis and Orthogonal Test Method

open access: yesSensors, 2022
The energy conversion of electromagnetic acoustic transducers (EMATs) is typically lower, which seriously restricts the application of EMATs in the field of non-destructive testing and evaluation. In this work, parameters of surface wave EMATs, including

Scarred patterns in surface waves [PDF]

open access: yesPhysical Review E, 2001
Surface wave patterns are investigated experimentally in a system geometry that has become a paradigm of quantum chaos: the stadium billiard. Linear waves in bounded geometries for which classical ray trajectories are chaotic are known to give rise to scarred patterns.

Excite Spoof Surface Plasmons with Tailored Wavefronts Using High‐Efficiency Terahertz Metasurfaces

open access: yesAdvanced Science, 2020
Spoof surface plasmons (SSPs) play crucial roles in terahertz (THz) near‐field photonics. However, both high‐efficiency excitation and wavefront engineering of SSPs remain great challenges, which hinder their wide applications in practice. Here, a scheme

Seismological reference earth model in South China (SREM-SC): Upper mantle

open access: yesFrontiers in Earth Science, 2023
This work is the mantle component of constructing the Seismological Reference Earth Model in South China (SREM-SC). Although there has been a wide range of research for imaging the upper mantle structures beneath South China, most of them focus on the ...

Surface Wave Attenuation in Multilayer Structures With Lossy Media and Impedance Surfaces

open access: yesIEEE Access, 2021
A methodology to analyze the attenuation constant of surface wave propagating in general multilayer structures is proposed. The multilayer structure may include any number of layers, that can be made up of lossy dielectric, magnetic-material, and ...

Surface-Wave Extraction Based on Morphological Diversity of Seismic Events

open access: yesApplied Sciences, 2018
It is essential to extract high-fidelity surface waves in surface-wave surveys. Because reflections usually interfere with surface waves on X components in multicomponent seismic exploration, it is difficult to extract dispersion curves of surface waves.
