  Aharonov-Bohm electrodynamics predicts the existence of traveling waves of
pure potentials, with zero electromagnetic fields, denoted as gauge waves, or
g-waves for short. In general, these waves cannot be shielded by matter since
their lack of electromagnetic fields prevents the material from reacting to
them. However, a not-locally-conserved electric current present in the material
does interact with the potentials in the wave, giving the possibility of its
detection. In [F.M., G.M., Eur.Phys.J. C 83, 1086 (2023)] the basic theoretical
description of a detecting circuit was presented, based on a phenomenological
theory of materials that can sustain not-locally-conserved electric currents.
In the present work we discuss how that circuit can be built in practice, and
used for the effective detection of g-waves.
