3.3.2.17. A_FMM.Stack.join

Stack.join(st2: Self) → None

Join the scattering matrix of the structure with the one of a second structure

When doing this, the lenght of the first al last layeror each stack are ignored (set to 0). To function last layer of self and first of st2 need to be equal (but do not need to have physical meaning). The condiction used to previoselt solve the stack needs to be the same. This is not checked by the code, so be careful.

Parameters:

st2 (Stack) – Stack to which to join self.

Raises:

RuntimeError – Raised is one the structure is not solved yet.

Returns:

None.
