# AnisotropicMedium

Diagonally anisotripic medium.

# Name

name: Optional unique name for medium.

# Thermal Properties

This section appears when the task group includes a Heat solver and is omitted from a standalone FDTD task.

# Medium Type

type: Selects the thermal model under Medium Type.

Type: string

Options:

  • FluidSpec: The Heat solver does not solve for temperature in regions that use this medium.
  • SolidSpec: The Heat solver uses the solid thermal model.

Default: SolidSpec for a new medium in a Heat simulation.

# Thermal Conductivity

conductivity: Thermal conductivity. This field is shown when Medium Type is SolidSpec.

Type: floating-point number

  • Unit: W/(μm·K)
  • Constraint: greater than 0
  • Required field

NOTE

The editor has no inputs for heat capacity (capacity) or density (density). When you create a medium in a Heat simulation, the editor sets capacity to 1. To set other values, use the Python interface. See Thermal Properties for the API fields.

# Optical Properties

# Diagonal Components

xx: Medium describing the xx-component of the diagonal permittivity tensor.

yy: Medium describing the yy-component of the diagonal permittivity tensor.

zz: Medium describing the zz-component of the diagonal permittivity tensor.

Options:

# Advanced

frequency_range: Optional lower and upper frequency bounds for the medium.

Type: pair of floating-point numbers

  • Unit: Hz for both values
  • Constraint: each value greater than 0
  • Default: None

# Appearance

Appearance settings control the medium’s face color and transparency in the model view. They do not change the optical properties.
