N2 - The electron transmission through a closed Aharonov-Bohm mesoscopic solid-state interferometer, with a quantum dot (QD) on one of the paths, is calculated exactly for a simple model. Although the conductance is an even function of the magnetic flux (due to Onsager’s relations), in many cases one can use the measured conductance to extract both the amplitude and the phase of the “intrinsic” transmission amplitude [Formula presented] through the “bare” QD. We also propose to compare this indirect measurement with the (hitherto untested) direct relation [Formula presented].
