solprop.modes

Waveguide modes.

The mode protocol, capillary, rectangular and planar modes, transverse quadrature and mode collections (physics layer).

Modules

antiresonant	Single-ring tube-lattice modes with the Vincetti empirical fits.
base	Derived quantities of any mode: beta, alpha, group delay, dispersion, ZDW.
capillary	Marcatili modes of a gas-filled hollow capillary, with analytic derivatives.
collection	Ordered, validated sets of modes, and the overlaps between them.
connection	Derive the connection of a basis whose material interfaces move along z.
fill	Share gas-fill resolution, freezing and loss policy across hollow-waveguide modes.
graded_index	Solve radial TE/TM Maxwell sectors and a separately labelled LP approximation.
guide	Build Poynting-normalised bound-mode providers with explicit material ownership.
material	Describe material laws and region ownership independently of longitudinal paths.
protocol	The mode protocol: what the rest of solprop needs from a waveguide mode.
quadrature	Fixed transverse quadrature rules and the mode matrices built on them.
rectangular	Model gas-filled rectangular waveguides with dielectric or metallic walls.
slab	Model the hollow planar (slab) waveguide: two plates, a gas-filled gap, uniform y.
stepindex	Solve the exact, lossless vector eigenproblem of a circular step-index fibre.
tabulated	Build waveguide modes from loaded effective-index arrays.
vector	Represent internal-convention Maxwell samples on physical area quadrature.
