# PolderTensor

The parameters used to define a Polder tensor.

## Example

app = cf.GetApplication()
project = app:NewProject()

-- Create an anisotropic 3D medium using a Polder tensor definition

properties = cf.AnisotropicDielectric.GetDefaultProperties()
properties.TensorDescription = cf.Enums.TensorDescriptionMethodEnum.PolderTensor
-- Dielectric modelling
properties.PolderTensor.RelativePermittivity = "14.5"
properties.PolderTensor.LossTangent = "0.0"
-- Magnetic medium properties
properties.PolderTensor.SaturationMagnetisation = "650.0"
properties.PolderTensor.LineWidth = "0.0"
-- Magnetostatic bias field
properties.PolderTensor.DCBiasField = "220.0"
properties.PolderTensor.FieldDirection = cf.Enums.MagnetostaticFieldDirectionEnum.ZDirected

-- Change the colour to Cyan

anisotropicDielectric.Colour = "#00FFFF"


## Usage locations (object properties)

The following objects have properties using the PolderTensor object:

## Property List

DCBiasField
The magnetic bias field applied to the 3D anisotropic medium. This value is given in Oersted. The direction is defined using the FieldDirection enumeration property. (Read/Write Expression)
FieldDirection
The orientation of the DCBiasField. (Read/Write MagnetostaticFieldDirectionEnum)
LineWidth
The line width or delta H represents the rate that the precessional mode, in the biased ferrite, will decay when the excitation is removed. This is measured in Oersted. (Read/Write Expression)
LossTangent
Dielectric loss tangent value. . (Read/Write Expression)
RelativePermittivity
Dielectric relative permittivity value. (Read/Write Expression)
SaturationMagnetisation
The magnetisation value at which all the magnetic dipole moments of the material become aligned. (Read/Write Expression)
