FresnelPropagator

class abtem.multislice.FresnelPropagator

Bases: object

The Fresnel propagator is used for propagating wave functions using the near-field approximation (Fresnel diffraction).

get_array(waves, thickness)	rtype: ndarray
propagate(waves, thickness[, in_place])	Propagate wave functions through free space.

propagate(waves, thickness, in_place=False)

Propagate wave functions through free space.

Parameters:

• waves (Waves) – The wave functions to propagate.

• thickness (float) – Distance in free space to propagate.

• in_place (bool) – If True, the waves are overwritten.

Returns:

propagated_wave_functions – Propagated wave functions.

Return type:

Waves
