AddDebyeMaterial
================
```{function}  AddDebyeMaterial(CSX, name, varargin)
```
Full definition:
```{code-block} matlab
function CSX = AddDebyeMaterial(CSX, name, varargin)
```

Add a Debye type dispersive material model.

The Debye type frequency dependent material:

    eps_r(w) = eps_r + sum_p ( eps_r_delta,p / (1+jw*t_relex,p) ) - j*kappa/w

with
- eps_r_delta,p: the delta electric relative permitivity
- t_relex,p:     the electric relaxation time

Use SetMaterialProperty to define the material constants:
- 'EpsilonDelta_p':      p-th eps_r_delta,p
- 'EpsilonRelaxTime_p':  p-th t_relex,p

example:

    CSX = AddDebyeMaterial(CSX,'debye');
    CSX = SetMaterialProperty(CSX,'debye','Epsilon',5,'EpsilonDelta_1',0.1,'EpsilonRelaxTime_1',1e-9);
    [..]
    CSX = AddBox(CSX,'debye', 10 ,start,stop);
