PyStratify against PyMoosh

← Verification · Thin films · Point dipole

Reference: PyMoosh modes.guided_modes
Kind: code: another group's code
Calculated: every guided n_eff (TE and TM) of four lossless guides against FilmSource.guided_poles, the poles behind the guided channel
Agreement: 1e-9 (PyMoosh's search stops at 1e-10); observed ≤ 1.1e-11

A symmetric slab of n = 2 in air, 633 nm: the guided modes PyStratify finds against PyMoosh's mode solver Every TE and TM mode, numbered from the highest index: the poles PyStratify finds behind a dipole's guided channel against PyMoosh's guided_modes (its search stops at 1e-10). A mode appears at its cutoff, n_eff = 1. The test runs four guides.
