dyna.functions.Functions module
Functions.
@author: Stephane Grenier, Institut Néel, CNRS, France TODO : keep M matrices in memory so as to not have to recalculate them for Transmittance or Kerr.
- dyna.functions.Functions.F0(_Sequence, _Sample, _XRange, _EnergyRange, _AngleRangeRad, _SF_SIM)[source]
F0 : Parratt formalism.

_Factor = (cst.h/np.pi)**2/(4*cst.epsilon_0)/cst.m_e * 1e30 / np.square(_EnergyRange) 2*2*np.pi/(cst.h*cst.c)*cst.e *1e-10 = 1.01355 e-3, in A-1
Parameters
- _SequenceTYPE
contains the sequence of the multilayer
- _SampleTYPE
DESCRIPTION.
_XRange : TYPE
- _EnergyRangeTYPE
DESCRIPTION.
- _AngleRangeRadTYPE
DESCRIPTION.
- _SF: TYPE
Scattering Factors for the current simulation Shape is [len(Sample), len(energy), 2]
Returns

- dyna.functions.Functions.F0F1Farad(_Sequence, _Sample, _XRange, _EnergyRange, _AngleRangeRad, _SF, _pi_incident)[source]
F0F1Farad calculates the Faraday effect.
This is supposing that the rotation and the ellipticity are small enough to justifiy the expression. One needs to check this accordingly.
