PyStratify against treams: chiral shells

← Verification · Spheres · Plane wave

Reference: treams, chiral shells
Kind: code: another group's code
Calculated: helicity T-matrix of three chiral multilayers (gold, magnetic and gain-in-κ shells)
Agreement: 1e-11; observed ≤ 6.1e-14

A chiral shell (κ = 0.05 + 0.01i, 40/55 nm) in water: the helicity T-matrix against treams treams (Beutel et al.) builds a chiral multilayer's T-matrix in the helicity basis from its own vector spherical waves; the two helicities differ because the shell is chiral. The test covers three chiral multilayers (gold, magnetic, gain in κ).
