Module cartesian 

Spherical translation coefficients of single mode pairs at Cartesian displacements, with their displacement and wavenumber derivatives.

treams-rs extension: treams evaluates translations at polar arguments only.

Structs

CartesianTranslation

Translation coefficient with its Cartesian and wavenumber derivatives.

Functions

cartesian_translation

Translation coefficient of the source mode from to the destination mode to, with its derivatives.

combine 🔒

z_p(k r) Y and its displacement and wavenumber derivatives away from the origin, from the unit-sphere harmonic Y at the direction unit and its tangential gradient (see crate::special::tangent).

harmonic 🔒

z_p(k r) P_p^m(cos theta) exp(i m phi) and its displacement and wavenumber derivatives, from the radial jet at k r and the displacement’s direction (None at the origin and at subnormal displacements).
