¶
Gradients simplification.
This module contain functions to simplify gradient layers for optical calculations. Each such layer is replaced with two uniform layers providing the same transfer matrix. Using such simplified gradients for optical computations strongly improves the accuracy and speed of optical computations.
For details see: M. Wasiak, M. Dobrski…
Functions¶
simplify (item, lam[, T, linear, dT]) |
Return stack of two layers providing the same optical parameters as the gradient layer. |
simplify_all (geometry, lam[, T, linear, dT]) |
Replace all rectangular blocks with gradients with two-layer simplification in geometry tree. |

simplify
(item, lam, T=300.0, linear='nr', dT=100.0)¶ Return stack of two layers providing the same optical parameters as the gradient layer.
Parameters: Returns: an object replacing the original leaf
Return type:
-
plask.util.gradients.
simplify_all
(geometry, lam, T=300.0, linear='nr', dT=100.0)¶ Replace all rectangular blocks with gradients with two-layer simplification in geometry tree.
Parameters: - geometry (GeometryObject) – object to simplify
