CoupledTwoPorts

Bases: Model

(experimental) Wraps N 2-port models (e.g., Inductors) and couples them via a given K-matrix.

Returns a 2N-port model where Model 1 occupies ports (0, 1), Model 2 occupies ports (2, 3), and so on.

Parameters:

coupled (list[Model]) – The sequence of 2-port series models to couple.
k_matrix (ArrayLike) – The NxN coupling coefficient matrix. Must be symmetric, have 1.0 on the diagonals, and be positive semi-definite.

Builds of model of coupled two-ports from a list of couplings coefficients between them.

Parameters: - models: The models to be coupled. - defined_couplings: A list of tuples (model_i, model_j, k_factor).

coupled: list[Model]: The sequence of 2-port series models to couple.
