An example python-meep simulation of how metamaterial parameters can be retrieved in a more reliable way when the MM unit cell is excited by a volume source with a given K-vector.

##Examples of metamaterial scattering parameters computation

• ?? Slab made of dielectric
• ?? Wires [metallic wires oriented along electric field]
• ?? Cut wires parallel to E
• ?? Rod array parallel to H
• ?? SRRs
• ?? Wire pairs
• ?? Dielectric spheres
• ?? Dielectric spheres with wires
• ?? Rod array parallel to E
• ?? Fishnet
• ?? Metallic slab parallel to the magnetic field
