acoustotreams.pamplitudeff(r, *, basis, k0, material=AcousticMaterial(1.3, 343.0, 0.0), modetype=None)[source]

Far-field amplitude of pressure field.

The resulting matrix maps the scattered pressure field coefficients in the scalar spherical or cylindrical wave basis to the far-field amplitude of the pressure field.

The far-field amplitude is given in units of N/m.

Parameters:

  • r (array_like) – Evaluation points.

  • basis (ScalarBasisSet) – Basis set.

  • k0 (float) – Angular wavenumber in the air. Has units of 1/r.

  • material (AcousticMaterial or tuple, optional) – Material parameters. Defaults to the air.

  • modetype (str, optional) – Mode type.
