`DielectricFrequencyCollection`

A collection of frequency points modelling the dielectric properties.

## Example

app = cf.GetApplication() project = app:NewProject()-- Create a dielectric mediumdielectric = project.Media.Library:AddToModel("Construction_glass")-- Get the loss tangent for the second frequency point in the collectionlossTangent = dielectric.DielectricModelling.FrequencyPoints[2].LossTangent

## Property List

## Method List

- Add (
`frequency`Expression,`relativepermittivity`Expression,`conductivity`Expression) - Add a frequency point of dielectric properties to the dielectric medium. For the loss tangent or conductivity value, both will be set to the given value. The active one is specified by the ConductivityType property. This method is only valid when the DielectricModelling DefinitionMethod is FrequencyList.
- Item (
`index`number) - Returns the DielectricFrequencyPoint at the given index. (Returns a DielectricFrequencyPoint object.)
- Modify (
`index`number,`frequency`Expression,`relativepermittivity`Expression,`conductivity`Expression) - Modify the frequency point of dielectric properties at the given index. For the loss tangent or conductivity value, both will be set to the given value. The active one is specified by the ConductivityType property. This method is only valid when the DielectricModelling DefinitionMethod is FrequencyList.
- Remove (
`index`number) - Remove the frequency point of dielectric properties at the given index. This method is only valid when the DielectricModelling DefinitionMethod is FrequencyList.
