fields.propagate_amplitude

fields.propagate_amplitude​

Propagates waves with the given amplitude by distance.

The propagation is along the wave direction, i.e. when distance is positive, amplitudes for forward-propagating waves are those associated with a positive shift along the z-axis, while the reverse is true for backward-propagating wave amplitudes.

Args:​

  • amplitude: The amplitudes to be propagated, with a trailing batch dimension.
  • distance: The distance to be propagated.
  • layer_solve_result: The result of the layer eigensolve.

Returns:​

  • None: The propagated amplitudes.
