Abstract :
The ac sheet conductance of large two-dimensional arrays of proximity effect SNS Josephson junctions was measured as a function of temperature, frequency and applied perpendicular magnetic field. A quantitative analysis of the data shows that the normal to superconducting transition of unfrustrated arrays follows the predictions of the Kosterlitz-Thouless theory for phase transitions in two dimensions.
