XML File Format for Importing Media
View the .xml file format that describes the medium properties of a dielectric, metal or impedance sheet.
Overview
- Define the frequency independent (static) properties for the medium using keywords.
- Define the frequency dependent properties for the medium using keywords.
Keywords for the .xml file
Use the following keywords to define the medium:
- Dielectric
- freq, permittivity, diel_loss_tangent, mag_loss_tangent, conductivity, permeability.
- Metal
- freq, conductivity, permeability, mag_loss_tangent.
- Impedance sheet
- freq, surf_imp_re, sur_imp_im
Example of a .xml file
The following is an example of a .xml file that describes a medium with frequency independent (static) values as well as measured frequency independent values.
