Irradiation of HTS Josephson junctions with the surface wave resonator

The new type of surface wave resonator (SWR) consists of HTS film on a dielectric substrate is developed. A possibility of optimal coupling between the electromagnetic field of the SWR and the HTS Josephson junction array is shown; The topologies for embedding the bicrystal HTS Josephson junctions in the SWR are developed. These topology ensure the junction synchronization, that can be used for creation voltage standards, microwave detectors and Josephson generators and so on; The microwave properties of the SWR with HTS Josephson junction arrays (up to 450 junctions) and nonlinear elements based on Shottky-barrier diodes have been investigated. For the array with 450 HTS Josephson junctions the voltage sequence with 10 mV step has been obtained, sensitivity of the detector based on this array is 0.1 A/W with dynamic range 10² dB; The Josephson generation with microwave power at several nW for the SWR with bicrystal HTS JJs is detected. There were two groups of junctions. These groups are formed at the time of fabrication due to imperfection of HTS junction fabrication technology.
