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.

Mathematical Model of the On-Board Antenna of Reentry Spacecraft Taking into Account Surface Waves

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2022
Introduction. The onboard antennas of the returned hypersonic aircraft are weakly directional, which is achieved by radiation from the open end of the waveguide. When passing through dense layers of the atmosphere, they are exposed to aerodynamic heating,

Surface wave tomography [PDF]

open access: yesEos, Transactions American Geophysical Union, 1984
Surface waves are now being used by several groups to map lateral heterogeneity [Nakanishi and Anderson, 1982, 1983, 1984a, b; Woodhouse and Dziewonski, 1984] and anisotropy [Tanimoto and Anderson, 1984a, b; Nataf et al. 1984] of the upper mantle on a global basis.

Propagation of Surface Waves in a Rotating Coated Viscoelastic Half-Space under the Influence of Magnetic Field and Gravitational Forces

open access: yesFractal and Fractional, 2021
The present manuscript focuses on the study of surface wave propagation in a rotating coated viscoelastic half-space and its response to external forces comprised of the magnetic field and gravitational forces. A celebrated normal mode analysis procedure

Low-Loss Light Guiding at the Subwavelength Scale in a Nanowire-Loaded Hybrid Bloch-Surface-Polariton Waveguide

open access: yesIEEE Access, 2020
We report the realization of strongly confined low-loss optical waveguiding at telecommunication wavelength by exploiting the hybridization of photonic modes guided by coupled dielectric mode and Bloch surface polaritons on the interface between one ...
