Modules

susceptibilities

Module for computing the dynamic magneto-optic susceptibility tensor components for a given dynamic magnetization vector.

Classes

ObjectiveLens

Class for calculation of the focal electric fields of given lens.

Functions

get_signal_GF_focal(SweepBloch, KxKyBloch, ...)	Compute Brillouin light scattering (BLS) spectrum using the Green function formalism.
getBLSsignal(SweepBloch, KxKyBloch, Bloch, ...)	Compute Brillouin light scattering (BLS) spectrum using the Green function formalism.
get_signal_RT_pupil(KxKy, Ei_fields, ...[, ...])	Compute Brillouin light scattering (BLS) spectrum using the reciprocity theorem, starting directly from the electric fields in reciprocal (k) space.
get_signal_RT_focal(Exy, Ei_fields, ...[, ...])	Compute Brillouin light scattering (BLS) spectrum using the reciprocity theorem.
get_signal_RT_focal_3d(Exy, Ei_fields, ...)	Compute Brillouin light scattering (BLS) spectrum using the reciprocity theorem, evaluating signal contribution from multiple depths.
fresnel_coefficients(lambda_, DF, PM, d, ...)	Create functions, htp and hts, that compute the Fresnel transmission coefficients for p- and s-polarized light, respectively, for a given lateral wavevector q.
sph_green_function(Kx, Ky, DFMagLayer, ...)	Compute the spherical Green's functions for p- and s-polarized fields.

Example

The usage of this submodule is not as straightforward as for the rest of the SpinWaveToolkit, and therefore the reader is referred to the relevant Examples.
