摘要：

Superconducting granular thin films are considered to be an array of Josephson junctions and can be used as fast, sensitive detectors of microwave and submillimeter wave radiation. Experimental results on detection of 10 GHz and HCN laser radiation with tin granular thin films are described. The responsivity is 9 multiplied by 10**6 V/W at 10 GHz which is higher than that of single point contact Josephson junctions. This result can be explained by the addition of each detection voltage. The granular thin films can be used as a sensitive detector having higher responsivity over the single Josephson junction.
