Weighting is usually defined as 1 if each layer's parameters are calculated by user or GUI program.

However, if it is not equal to 1, all parameters such as $\Delta_1$ $\Delta_2$ $\Delta_3$ a c $c_{11}$ $c_{12}$ $c_{13}$ $c_{33}$ $c_{44}$ $c_{66}$ $D_1$ $D_2$ $D_3$ $D_4$ $D_5$ $D_6$ will be weighted by

 n_layer_parameters = Weighting(n_layer_parameters) + (1-Weighting)*last_layer_parameters  

For example, if we have 5 layers, and weighting of the second layer is 0.5, then  

  $\Delta_{1} (2)$  = $\Delta_{1} (2) * Weighting_2 + \Delta_{1} (5) * (1-Weighting_2)$

The $calculatekp setting for 1D-DDCC in GUI interface
1.Press the kp and Polarization.
2.Press the Calculate kp.
$calculatekp will only appear in the input file if Calculate kp is pressed.

$\theta$ , $\phi$ setting in Epitaxial Layer.
After modifying the parameters, you need to press number 5 to update the data.

Other parameters can be found in kp and Polarization.
Number 6 can modify"kx_nmax, ky_nmax, dk".
7.Press the kp table will show on Number 8.
8.Choose you need parameters,they will show on Number 9.
9.You can modify parameters in Number 9.
