PyStratify against smuthi

← 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.

smuthi computes with T-matrices with Sommerfeld integrals. Each case computes the same quantity with PyStratify and with smuthi and plots both on the same axes.
