acoustotreams.spw.to_ssw(l, m, kx, ky, kz)

Coefficient for the expansion of a scalar plane wave in scalar spherical waves

Returns the coefficient for the basis change from a scalar plane wave to a scalar spherical wave. For multiple positions only diagonal values (with respect to the position) are returned.

Parameters:

• l (int, array_like) – Degree of the scalar spherical wave

• m (int, array_like) – Order of the scalar spherical wave

• kx (float, array_like) – X component of scalar plane wave’s wave vector

• ky (float, array_like) – Y component of scalar plane wave’s wave vector

• kz (float, array_like) – Z component of scalar plane wave’s wave vector

Returns:

complex
