Define a medium with specific material properties, import a predefined medium from the
media library or add a medium from your model to the media library.
Note: Only passive media are supported. Passive media can be
either lossless or lossy.1
The following media types are supported:
Dielectric
Metal
Layered dielectric (isotropic and anisotropic)
Impedance sheet
Characterised surface
Windscreen layer
Anisotropic medium (3D)
Media are displayed in the model tree. This includes user-defined media and
media added from the media library.Figure 1. The media definitions in the model tree
The colour square next to each medium entry indicates the colour that is used to display the
medium in the 3D view as well as in POSTFEKO. To change
the display colour, click the dielectric in the model tree and from the right-click context menu, select Change display colour.
Predefined Media
Predefined media are available by default in CADFEKO and includes
Perfect electric conductor, Perfect magnetic
conductor and Free space.Figure 2. The predefined media in the model tree
Tip: Edit the properties of free space if the model is inside an infinite
medium.
1 A lossless passive medium allows fields to pass
through the medium without attenuation. In a lossy passive medium, a
fraction of the power is transformed to heat, as an example.
