This is called aOn page 4 of multiplex1 , you find:

[...] a multiplex network can be represented as a collection of graphs $$\mathcal{G}=\{G^{(\ell)}=(V_n,E^{(\ell)})\}_{\ell \in V_L}$$ where $V_n=\{1,\ldots,n\}$ is the set of nodes, $V_l=\{1,\ldots,L\}$ s the set of layers and $E^{(\ell)}\subset V_n\times V_n$ is the set of edges on layer $\ell$.

These structures are also sometimes called multi-layer graph or complex networkgraphs (depends where you look. Note that in the literature).

See for instance (1)above formulation it is assumed that the nodes on each layer are the same (in particularthis models the introductionbijective edges you are referring to), for more references on complex networks.
