acoustotreams.ssw.periodic_to_scw(kz, m, l, mu, k, area)[source]

Convert periodic spherical wave to cylindrical wave.

Returns the coefficient for the basis change in a periodic arrangement of spherical modes to cylindrical waves. For multiple positions only diagonal values (with respect to the position) are returned.

Parameters:

  • kz (float, array_like) – Z component of destination mode wave vector

  • m (int, array_like) – Order or the destination mode

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

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

  • k (float or complex, array_like) – Wave number

  • area (float, array_like) – Unit cell area

Returns:

complex
