At this frequency, the silver behaves approximately as a perfect electric conductor, and the SPP is called a Sommerfeld–Zenneck wave, with almost the same wavelength as the free-space wavelength. The surface plasmon polariton (SPP) is an electromagnetic surface wave that can travel along an interface between two media with different ...

Rayleigh waves are distinct from other types of surface or guided acoustic waves such as Love waves or Lamb waves, both being types of guided waves supported by a layer, or longitudinal and shear waves, that travel in the bulk. Rayleigh waves have a speed slightly less than shear waves by a factor dependent on the elastic constants of the ...
Since Rayleigh waves are composed of P and S-waves and Love waves are composed of only S waves, Haskell derived the elastic wave equations for both P and S-waves. These equations were modified to show Rayleigh wave motion. After assuming a free surface boundary where no stresses or strains cross, the Rayleigh wave equation is simplified.
Love waves are horizontally polarized shear waves (SH waves), existing only in the presence of a layered medium. [9] They are named after Augustus Edward Hough Love, a British mathematician who created a mathematical model of the waves in 1911. [10] They usually travel slightly faster than Rayleigh waves, about 90% of the S wave velocity.
Waves battered the shores of San Luis Obispo County Thursday morning as high tides washed onto streets, closed piers and parking lots and prompted multiple water rescues up and down the coast.

The national polling average released by Silver on Sunday morning showed Harris over Trump 48.5% to 47.6%. But he cautioned his model doesn’t care about the national polls as much at this stage.
