surface wave

n.
A seismic wave that travels across the surface of the earth rather than through it. Surface waves usually travel more slowly and have larger amplitudes and longer wavelengths than body waves.

surface wave

An earthquake wave in which rock particles vibrate at right angles to the direction of wave travel. Surface waves travel only on the Earth's surface, and not through it. Also called L wave. See Note at earthquake.

For the linearly polarized backscattering cross section, the quad-polarized covariance matrix is used for the ocean surface wave polarization signatures, as follows [31]:
The design of the mushroom-like EBG structure was based on the high-impedance surface (HIS) principle [6] and subsequently incorporated onto the antenna substrate for suppressing the surface wave [7].
To estimate these characteristics, we applied five geophysical methods: spectral ratio (HIV), frequency-wavenumber (F-K), multichannel analysis of surface waves (MASW), multichannel analysis of microtremor (MAM), and gravimetric method.
(94) This method is particularly feasible for locating sources using surface wave propagation for frequencies above 0.05 Hz because it is less sensitive to uncertainties associated with strong lateral heterogeneity in the crust than the beamforming method is.
In the aspect of advanced detection of surface wave and scattered wave in underground coal mine, the advanced detection technique of Rayleigh surface wave was carried out in Fangezhuang Mine (Cheng et al., 2014).
At resonance frequency, high impedance could be obtained and hence the EBG do not support any surface wave near the resonance frequency, resulting in a frequency band gap.

Storms moving over the ocean can leave "secret" traces on the seafloor known as ripple bedforms, which develop when surface waves create seafloor currents that disrupt sediment and form ripples on the ocean floor.
Bloch surface waves (BSW) are light waves that travel on the surface of insulating - or "dielectric" - materials, such as glass.
The underlying design approach has much wider applications, ranging from microwave to optics for the control of any kind of electromagnetic surface waves.
