Module cartesian 

Cartesian cylindrical-wave translation and analytic derivatives.

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

Structs

CartesianTranslation

Translation coefficient and its continuous derivatives, with the axial wavenumbers of both modes moving together.

Functions

cartesian_translation

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

regular_harmonic 🔒

Regular J_m harmonic as a Cartesian power series, for |k_rho rho| below SERIES_RADIUS. Factoring the azimuthal polynomial keeps derivatives regular on the cylinder axis.
