Module coeffs

Expand description

Mie coefficients of multilayer chiral spheres and cylinders, and the materials they take.

Each pullback runs on the calling thread and adds its terms in a fixed order, so the Rayon pool does not change the gradients.

Modules§

material 🔒: Isotropic, optionally chiral materials and the validation of concentric layers.
mie 🔒: Mie coefficients of multilayer chiral spheres and their analytic pullback.
mie_cyl 🔒: Mie coefficients of multilayer chiral cylinders and their analytic pullback.

LayerGradient: Gradients of concentric layers: the radii of their boundaries and their media.
Material: Isotropic reciprocal material, optionally chiral.
MieCylGradient: Gradients of the inputs of mie_cyl, in the order of its arguments.
MieCylResidual: What mie_cyl saves for its pullback: the four-channel interface states and radial functions, so the pullback evaluates no Bessel functions.
MieGradient: Gradients of the inputs of mie, in the order of its arguments.
MieResidual: What mie saves for its pullback: the interface matrices and radial functions of one degree l, so the pullback evaluates no Bessel functions.

mie: Mie coefficients of degree l of a concentric multilayer chiral sphere.
mie_cyl: Mie coefficients of concentric chiral cylinders at the axial wavenumber kz and the azimuthal order m (order).
real_refractive_indices: Negative- and positive-helicity refractive indices sqrt(epsilon mu) -+ kappa of a real material.
