DI Card
This card can be used to define the frequency dependent or independent material characteristics of a dielectric medium, metallic medium or an impedance sheet.
In the Home tab, in the Define group, click
the 
Media icon. From
the drop-down list select the 
Dielectric (DI) icon.
Figure 1. The DI - Set medium properties dialog.
Parameters:
- Medium label
- Label of the material to be defined.
- Define dielectric medium
- Define a dielectric medium by specifying a wideband model or loading points from a file and using linear interpolation. The following wideband models are available: Constant (Frequency independent), Debye relaxation, Cole-Cole, Havriliak-Negami and Djordjevic-Sarkar (Wideband Debye).
- Define metallic medium
- Define a metallic medium by specifying the frequency independent parameters or loading points from a file.
- Define impedance sheet
- Define an impedance sheet by specifying the frequency independent real/imaginary part of the impedance or loading points from a file.
- Define anisotropic medium
- Define an anisotropic medium by means of specifying either the Full tensor, Diagonal tensor, Complex tensor or Polder tensor (ferrites).
- Define characterised surface medium
- Define a characterised surface medium by loading the transmission and reflection coefficients from a .tr file.(as specified in the DA card)
- Source
- Define the medium by means of a wideband model or loading points from a file.
Note: The same functionality for defining a dielectric, metallic or impedance sheet is also
available in CADFEKO.
