Detailed Description
Classes and functions to describe magnetic and non-magnetic materials.
Function Documentation
◆ HomogeneousMaterial()
| Material HomogeneousMaterial | ( | const std::string & | name, |
| complex_t | refractive_index, | ||
| kvector_t | magnetization = {} |
||
| ) |
Constructs a material with name, refractive_index and magnetization (in A/m).
Alternatively, 
and 
for refractive index 
can be passed directly. With no parameters given, constructs default (vacuum) material with 
and zero magnetization.
◆ MaterialBySLD()
| Material MaterialBySLD | ( | const std::string & | name, |
| double | sld_real, | ||
| double | sld_imag, | ||
| kvector_t | magnetization = {} |
||
| ) |
Constructs a wavelength-independent material with a given complex-valued scattering length density (SLD).
SLD values for a wide variety of materials can be found on https://sld-calculator.appspot.com/ and https://www.ncnr.nist.gov/resources/activation/ By convention, SLD imaginary part is treated as negative by default, which corresponds to attenuation of the signal. With no parameters given, MaterialBySLD constructs default (vacuum) material with zero sld and zero magnetization.
- Parameters
-
name material name sld_real real part of the scattering length density, inverse square angstroms sld_imag imaginary part of the scattering length density, inverse square angstroms magnetization magnetization (in A/m)
