The material property is used for materials that are simply defined by the constant permittivity $ε r$ , magnetic permeability $μ r$ and electric conductivity $κ$ .

This material can be described as:

$\varepsilon(f) = \varepsilon_0\varepsilon_r - j\frac{\kappa}{2\pi f}$
and
$\mu(f) = \mu_0\mu_r - j\frac{\sigma_m}{2\pi f}$ ,where $σ m$ is the non-physical magnetic conductivity.

More complex, dispersive Materials can be defined using the Drude/Lorentz material model.

Description

A material property is added by

CSX = AddMaterial(CSX, name)

with the following parameters:

CSX: The original CSX structure
name: name of the assigned property, must be unique

Material Parameter Definition

The material parameters (e.g. permittivity, conductivity etc.) are defined using SetMaterialProperty:

CSX = SetMaterialProperty(CSX, name, varargin)

with the following parameters:

CSX: The original CSX structure
name: name of the material property (see above)

and the optional key/value parameter:

Epsilon: relative electric permittivity (must be >=1)
Mue: relative magnetic permeability (must be >=1)
Kappa: electric conductivity (must be >=0)
Sigma: magnetic conductivity (non-physical property, must be >=0)

Example

Add a non-magnetic material with $ε = 10.2$ :

CSX = AddMaterial(CSX,'MaterialName');
CSX = SetMaterialProperty( CSX, 'MaterialName', 'Epsilon', 10.2, 'Mue', 1 );
% add your primitives
