Module test_reflcalc

Return reflectivity R^2 from slab model with sharp interfaces. returns reflectivities.

The parameters are as follows:

Q (angstrom**-1)

points at which to evaluate the reflectivity

depth (angstrom)

thickness of the individual layers (incident and substrate depths are ignored)

rho (microNb)

Scattering length density.

mu (microNb)

absorption. Defaults to 0.

sigma (angstrom)

interface roughness between the current layer and the next. The final layer is ignored. This may be a scalar for fixed roughness on every layer, or None if there is no roughness.

wavelength (angstrom)

Incident wavelength (only affects absorption). May be a vector. Defaults to 1.

This function does not compute any instrument resolution corrections.

Use reflectivity_amplitude to return the complex waveform.

Returns the complex reflectivity waveform.

See reflectivity for details.

Magnetic reflectivity for slab models.

Returns the expected values for the four polarization cross sections (++,+-,-+,--).

Return reflectivity R^2 from slab model with sharp interfaces. returns reflectivities.

The parameters are as follows:

Q (angstrom**-1)

points at which to evaluate the reflectivity

depth (angstrom)

thickness of the individual layers (incident and substrate depths are ignored)

rho (microNb)

Scattering length density.

mu (microNb)

absorption. Defaults to 0.

wavelength (angstrom)

Incident wavelength (only affects absorption). May be a vector. Defaults to 1.

rho_m (microNb)

Magnetic scattering length density correction.

theta_m (degrees)

Angle of the magnetism within the layer.

Aguide (degrees)

Angle of the guide field; -90 is the usual case

This function does not compute any instrument resolution corrections or interface diffusion

Use magnetic_amplitude to return the complex waveform.

Returns the complex magnetic reflectivity waveform.
