Microwave properties of the surface wave resonator (SWR) consist of high-temperature superconductor (HTS) film on dielectric substrate were investigated. The analysis of the systems is made for continuous HTS film and for a film with an array of HTS Josephson junctions (JJ). In the last case it was revealed the Josephson junction synchronization effect, occurred under the influence of electromagnetic field (EMF) of the SWR. Due to this effect it is possible to make devices with synchronized array of junctions. The Josephson generation of HTS JJ array, embedded in the SWR is investigated in the X-band.The essential advantages of thin film HTS surface wave resonators as the basic elements for the coupling optimization of EMF and HTS JJ arrays were shown in [I-51. These systems have a high homogeneity and a great value of microwave current in the film plane. They are of a great interest of creation the devices with HTS JJ arrays of ,low and medium integration levels [6, 7, 81 such as voltage standards, tunable generators and microwave detectors.The microwave properties of the SWR can be qualitatively deduced fiom the parallel-plate transmission line model with losses [9]. In general case the parallel-plate transmission line consists of two plane conductors of unequal thickness spaced by a dielectric layer. As it was shown in [lo] the eigenwaves in this system are Swihart-plasmon modes. For the definite model parameter relations these eigenwaves are. converted to wellknown cases of Swihart waves [ l l ] (approximation kd&<<1) or surface waves -plasmons [12] (approximation kd& >> 1 ) (Fig. 1). In the last case the surface electromagnetic wave propagates in the vicinity of one conducting strip, even if no second strip is present. The model is also adequate if the strips have infinite conductance, when the Swihart-plasmon mode is converted to an ordinary TEM wave, which exists only for two-strip systems (Fig. la).When the parallel-plate transmission line has finite size I along the propagation direction z, the transmission line is transformed to a resonator. Its fundamental mode is determined by this longitudinal size 1.The examples of SWR are single metal plate or film, plate or film on a dielectric substrate, metal-dielectric-metal structures and so on [ l , 31. In the particular case half-wave SWR can be created as a sandwich of HTS thin film * z z >Figure 1.

The possibilities and physical mechanisms of detection of microwave X-and Ka-band radiation by hightemperature superconducting (HTS) YBa 2 Cu 3 O 7-0.05 (YBCO) bicrystalline Josephson junctions (JJ) embedded in a surface wave resonator (SWR) are considered. Microwave detection was investigated experimentally by using a linear Josephson junction array (JJA) embedded in the SWR. Measurements were carried out starting from the critical temperature of HTS film (T = 92 K), down to the liquid nitrogen level (T = 77 K) and beyond (down to 20 K) using the Gifford-McMahon closed-cycle cryo-cooler. The sensitivity of such type of detectors was determined to be approximately 10 4 V/W.
