# ParametricComplexExpression

A complex expression is a Lua string that defines a complex expression.

## Example

application = cf.Application.GetInstance()
project = application:NewProject()

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

properties = cf.AnisotropicDielectric.GetDefaultProperties()
properties.TensorDescription = cf.Enums.TensorDescriptionMethodEnum.ComplexTensor

-- Set the Permittivity matrix using complex expressions

properties.ComplexTensor.Permittivity[1][1] = "14.5 + j*0.0"
properties.ComplexTensor.Permittivity[1][2] = "0.0 + j*0.0"
properties.ComplexTensor.Permittivity[1][3] = "0.0 + j*0.0"
properties.ComplexTensor.Permittivity[2][1] = "0.0 + j*0.0"
properties.ComplexTensor.Permittivity[2][2] = "14.5 + j*0.0"
properties.ComplexTensor.Permittivity[2][3] = "0.0 + j*0.0"
properties.ComplexTensor.Permittivity[3][1] = "0.0 + j*0.0"
properties.ComplexTensor.Permittivity[3][2] = "0.0 + j*0.0"
properties.ComplexTensor.Permittivity[3][3] = "14.5 + j*0.0"

-- Set the Permeability matrix using complex expressions

properties.ComplexTensor.Permeability[1][1] = "0.998 + j*0.0"
properties.ComplexTensor.Permeability[1][2] = "0.0 - j*0.008"
properties.ComplexTensor.Permeability[1][3] = "0.0 + j*0.0"
properties.ComplexTensor.Permeability[2][1] = "0.0 + j*0.008"
properties.ComplexTensor.Permeability[2][2] = "0.998 + j*0.0"
properties.ComplexTensor.Permeability[2][3] = "0.0 + j*0.0"
properties.ComplexTensor.Permeability[3][1] = "0.0 + j*0.0"
properties.ComplexTensor.Permeability[3][2] = "0.0 + j*0.0"
properties.ComplexTensor.Permeability[3][3] = "1.0 + j*0.0"
