For strip resistances of the order of 1 kΩ the superconducting transition of the network, as evidenced by AC conductance measurements is shown to be of the Kosterlitz-Thouless type. In a perpendicular magnetic field, flux quantization in the loops of the network leads to periodic oscillations of the magnetoconductance.text::journal::journal article::research article
