      abstract     = {We present a model study of an alternative implementation
                      of a two-port Hall-effect microwave gyrator. Our set-up
                      involves three electrodes, one of which acts as a common
                      ground for the others. Based on the capacitive-coupling
                      model of Viola and DiVincenzo, we analyze the performance of
                      the device and we predict that ideal gyration can be
                      achieved at specific frequencies. Interestingly, the
                      impedance of the three-terminal gyrator can be made
                      arbitrarily small for certain coupling strengths, so that no
                      auxiliary impedance matching is required. Although the
                      bandwidth of the device shrinks as the impedance decreases,
                      it can be improved by reducing the magnetic field; it can be
                      realistically increased up to $ 150 \mathrm{MHz}$ at
                      $50\mathrm{\Omega}$ by working at filling factor $\nu=10$.
                      We examine also the effects of the parasitic capacitive
                      coupling between electrodes and we find that, although in
                      general they strongly influence the response of device,
                      their effect is negligible at low impedance. Finally, we
                      analyze an interferometric implementation of a circulator,
                      which incorporates the gyrator in a Mach-Zender-like
                      construction. Perfect circulation in both directions can be
                      achieved, depending on frequency and on the details of the
                      interferometer.},
