Defining a Dielectric Medium

Create a new dielectric medium with the substrate parameters.

1. Open the Create dielectric medium dialog using one of the following workflows:
   • On the Construct tab, in the Define group, click the  Media icon. From the drop-down list, select the  Dielectric medium icon.
   • On the model tree, a right-click context menu is available on Media. From the drop-down list, select Dielectric medium.
2. On the Dielectric modelling tab, from the Definition method list, select Frequency independent.

Define a lossless dielectric for the substrate with a relative permittivity equal to 2.2. A variable, substrate_er, was defined with the value of 2.2.

3. Set the Relative permittivity to substrate_er.
4. For Dielectric loss tangent, keep the default value of 0.

   
   

   

   
   

5. Set the Label to substrate.
6. Click Create to create the dielectric and to close the dialog.
