Abstract
We have studied the effects of microwave radiation on superconducting tunnel junctions and on the critical currents of superconducting strips at 2.0 and 10.0 GHz. In the tunnel junctions both quantum mechanical and classical effects (photon-induced tunneling and classical rectification, respectively), were observed, but not gap enhancement. The application of microwave radiation on long, superconducting, thin-film bridges was found to increase their critical current. The microwave magnetic field was found to couple more efficiently to the superconductor. The increase in the critical current was found to be proportional to the square root of the incident power.
