Transmission measurements through three-port microwave graphs are performed, in analogy to three-terminal voltage drop devices, with orthogonal, unitary, and symplectic symmetry.
The terminal used as a probe is symmetrically located between two different chaotic subgraphs of the same mean density of states.
Each subgraph is connected to one port, the input and the output, respectively.
We find a good agreement with theoretical predictions, provided the effects of dissipation and imperfect coupling to the ports is considered.
This extends previous studies using an asymmetric probe position [1].
