pylops.avo.avo.zoeppritz_element¶

pylops.avo.avo.zoeppritz_element(vp1, vs1, rho1, vp0, vs0, rho0, theta1, element='PdPu')[source]¶

Single element of Zoeppritz solution.

Simple wrapper to pylops.avo.avo.scattering_matrix, returning any mode reflection coefficient from the Zoeppritz scattering matrix for specific combination of incident and reflected wave and a set of incident angles

Parameters:

vp1 : float: P-wave velocity of the upper medium
vs1 : float: S-wave velocity of the upper medium
rho1 : float: Density of the upper medium
vp0 : float: P-wave velocity of the lower medium
vs0 : float: S-wave velocity of the lower medium
rho0 : float: Density of the lower medium
theta1 : np.ndarray or float: Incident angles in degrees
element : str, optional: specific choice of incident and reflected wave combining any two of the following strings: Pd P-wave downgoing, Sd S-wave downgoing, Pu P-wave upgoing, Su S-wave upgoing (e.g., PdPu)

Returns:

refl : np.ndarray: reflectivity values for all input angles for specific combination of incident and reflected wave.
