Defining a Dielectric Using the Properties Method

Define the second dielectric with ${\epsilon }_{\text{r}}$ = 2.5, $\sigma$ = 1e-2 and with label Substrate2.

myProp = cf.Dielectric.GetDefaultProperties()
myDiel2 = myProject.Definitions.Media.Dielectric:AddDielectric(myProp)
myProp.MassDensity = "4"
myProp.Label = "Substrate2"
myProp.DielectricModelling.RelativePermittivity = "2.5"
myProp.DielectricModelling.ConductivityType = cf.Enums.MediumDielectricConductivityTypeEnum.Conductivity
myProp.DielectricModelling.Conductivity = "1e-2"
myDiel2:SetProperties(myProp)

Figure 1. A dielectric with ${\epsilon }_{\text{r}}$ = 2.5, $\sigma$ = 1e-2 and label Substrate2.

1. Create the second dielectric using the properties method:

   AddDielectric (properties table)

2. Since we want to know the properties for a Dielectric, search for Dielectric (object) in the Help¹.
3. In the Help, under Dielectric > Static Function List, note the following:

   GetDefaultProperties ()

4. Use GetDefaultProperties() to obtain the default properties of a dielectric:

   myProp = cf.Dielectric.GetDefaultProperties()

5. Specify the properties of the dielectric:
   1. In the Help, under Dielectric > Property List, note the properties of interest:
      • Label
      • DielectricModelling

      Set the Label property, for DielectricModelling we need to navigate deeper:

      myProp.Label = "Substrate2"

   2. In the Help, click on the link in Dielectric > Static Function List > (Read/Write DielectricModelling) to navigate to the dielectric modelling properties.
   3. In the Help, under DielectricModelling > Property List, note the properties of interest:
      • RelativePermittivity
      • Conductivity and ConductivityType

      Set the RelativePermittivity property, for Conductivity we need to navigate deeper:

      myProperties.DielectricModelling.RelativePermittivity = "2.5"

   4. In the Help, click on the link in DielectricModelling > Property List > ConductivityType > MediumDielectricConductivityTypeEnum.
   5. Specify that conductivity will be used as well as the value for the conductivity:

      myProp.DielectricModelling.ConductivityType = cf.Enums.MediumDielectricConductivityTypeEnum.Conductivity
      myProp.DielectricModelling.Conductivity = "1e-2"

6. Update myDielec1 with its new properties using SetProperties ():

   myDielec2:SetProperties(myProp)
