Module par_form

Form class for a substrate and a feature and functions for operating on it

Calculates the scattering resulting from the shape profile of individual features. This also calculates the scattering that results from the layers of the substrate. All calculation in this module are in the Born Approximation and for shapes that are parallelapiped.

Classes
	Substrate This contains variables to define a substrate
	Parallelapiped This contains variables to define a feature
	Lego_Model

Functions

form_loop(feature_form, qx, qy, qz)
This function creates the form factor for the sample.

Function Details

form_loop(feature_form, qx, qy, qz)

source code

This function creates the form factor for the sample. The substrate form factor and sample form factor are calculated separately. Tz_sub and Tz are vectors returned from the layer_loop function, so total_form_feature[:,i,j] assignment maps onto [qz,qx,qy] (why this order?)
