Microwave phenomena in thin- film Josephson junctions coupled to a contiguous microstrip resonator

A half-wavelength microstrip resonator has been used to couple microwave radiation between Josephson junctions and an external 50 Ω transmission line, and various microwave properties of these resonator-coupled junction devices have been studied. The advantages of these devices in applications including coherent radiation emission, 2e/h precision voltage sources, and parametric plasma-related effects are described.
