pyudv.attenuation.near_field_theoretical#

near_field_theoretical(r, rn)[source]#

Return the near field function.

Parameters:

  • r (scalar, array) – Radial coordinate.

  • rn (scalar, array) – Near field distance

Returns:

return the near field function.

Return type:

scalar, array

Examples

>>> r = np.linspace(0.1, 1, 100)
>>> rn = 0.2
>>> Psi = near_field_theoretical(r, rn)
