acoustotreams.ssw.translate

acoustotreams.ssw.translate(lambda_, mu, l, m, kr, theta, phi, singular=True)

Translation coefficient for spherical modes.

Returns the correct translation coefficient from :func:acoustotreams.ssw.tl_ssw, and :func:acoustotreams.ssw.tl_ssw_r or a combination thereof for the specified mode and basis.

Parameters:

• lambda (int, array_like) – Degree of the destination mode

• mu (int, array_like) – Order of the destination mode

• l (int, array_like) – Degree of the source mode

• m (int, array_like) – Order of the source mode

• kr (float or complex, array_like) – Translation distance in units of the wave number

• theta (float, array_like) – Polar angle

• phi (float, array_like) – Azimuthal angle

• singular (bool, optional) – If true, singular translation coefficients are used, else regular coefficients. Defaults to True.

Returns:

complex
