PyStratify against Meep

← Verification · Spheres · Point dipole

Under active development. Verification is growing as comparisons are added and rerun: the matrix, its figures and their presentation are not yet in their final form. Spotted an error, or missing a topic? Tell us.

Meep computes with finite differences in time. Each case computes the same quantity with PyStratify and with Meep and plots both on the same axes.
