3.7    Metallic

Metallic is a lossy metal.

Relative magnetic permeability Mu and electric conductivity Sigma can be declared.

When using lossy metal model it is required to choose also the option for the bandwidth for rigorous consideration of frequency-dependent skin effect (also available in the Circuit Settings dialogue). For more details regarding this medium type refer to Metallic model description.

Note that in case of metal objects, which diemensions with respect to wavelength cause that we deal with semi- or fully transparent objects, the lossy metal model is not adequate. In those cases it is recommended to use dielectric model (isotropic or anisotropic) to accurately model the wave penetration into this object. An example of such case is given in User Guide 3D: Salisbury screen absorber chapter.
