acoustotreams.AcousticSMatrices.propagation

classmethod AcousticSMatrices.propagation(r, basis, k0, material=AcousticMaterial(1.3, 343.0, 0.0))

S-matrix for the propagation along a distance.

This S-matrix translates the reference origin along r.

Parameters:

• r (float, (3,)-array) – Translation vector.

• basis (ScalarPlaneWaveBasis) – Basis definition.

• k0 (float) – Wave number in air.

• material (AcousticMaterial, optional) – Material definition.

Returns:
