Webb24 dec. 2024 · Here, we would like to use a non-zero slowness value to analyze the resolution of the seismic array. Note that, θ is the back-azimuth of the plane wave source. Let the back-azimuth of the incoming plane wave slowness vector be α, and we have θ + α = 3 / 2 π and c o s ( α) = − s i n ( θ), s i n ( α) = − c o s ( θ) Webb5 dec. 2002 · The slowness vector u points into the direction of wave propagation, and its modulus is the reciprocal of the wave speed. The ray parameter p and the horizontal …

Webb31 juli 2007 · The stationary slowness vector is, in general, complex valued and inhomogeneous. Its computation involves finding two independent real-valued unit vectors which specify the directions of its real and imaginary parts and can be done either by iterations or by solving a system of coupled polynomial equations. Webb1 juni 1997 · The slowness vector, which is typically transformed into bearing and velocity, is a key parameter used for identifying seismic phases and for event source location. … smaller print on screen

Webb26 nov. 2024 · The associated slowness vector of a particular reflected wave is resolved to yield its properties, i.e., phase velocity, attenuation angle, propagation direction and attenuation coefficient. A 4 × 4 energy matrix represents the energy fluxes of reflected waves and interaction energy. Webb22 nov. 2024 · The basic role in the expressions for the reflection and transmission coefficients is played by complex-valued slowness vectors of incident and transmitted waves. Real-valued parts of slowness vectors are called propagation vectors and imaginary parts are called attenuation vectors. Webbsurface.
