 Navigation: Scripting Language > Material database getsurfaceconductivity

For materials which use a surface conductivity material model (such as Graphene), this function returns the complex index of any material that is in the material database. The surface conductivity at the specified frequency is interpolated from the neighboring frequencies where the conductivity data is available. For a list of materials which use the surface conductivity model, see Material conductivity models.

 Supported Product: FDTD, MODE

 Syntax Description out = getsurfaceconductivity( "materialname", f); Returns the surface conductivity (in units of S) of the material with the given name. The surface conductivity is returned for the specified frequency f where f is in units of Hz. getsurfaceconductivity( "materialname", f, component); Optional argument component can be 1, 2 or 3 to specify the x, y or z component for anisotropic materials. The default is 1.
