$negfoverlapcalculation is the command to setup the region of surface roughness. The first term is to setup what kind of structure, 1 is circle, and 2 is rectangular for cross section region. If the first term is 1, then the four parameters after that are fix factor for surface roughness scattering, root mean square height<math>\Delta</math>of surface roughness, diameter of the outer circle, and the diameter of the inner circle. If the first term is 2, then the four parameters after that are fix factor for surface roughness scattering, root mean square height<math>\Delta</math>of surface roughness, width, and height.<br> |

$negfoverlapcalculation is the command to setup the region of surface roughness. The first term is to setup what kind of structure, 1 is circle, and 2 is rectangular for cross section region. If the first term is 1, then the four parameters after that are fix factor for surface roughness scattering, root mean square height
of surface roughness, diameter of the outer circle, and the diameter of the inner circle. If the first term is 2, then the four parameters after that are fix factor for surface roughness scattering, root mean square heightof surface roughness, width, and height.
