3.2.6.24. A_FMM.Layer.overlap

Layer.overlap(u: ndarray, up: ndarray = None)

EXPERIMENTAL: Calculates overlap between two fields given the modal expansion

Parameters:

• u (1darray) – Modal coefficient of first mode.

• up (1darray, optional) – Modal coefficient of first mode. Defaults to None (up=u, namely normalization is returned).

Returns:

[tx, tx]: floats. Namely overlap in x and y polarization

Return type:

list
