MILLIMETER WAVES DETECTOR BASED ON JOSEPHSON’s JUNCTIONS WITH OPTIMAL SUBSTRATE

The detectors based on superconductors are used for the registration of signals in the millimeter range [1]. Specially, the quantum radio receptor is widely used due to its very high sensibility. The structure of such receptor consists usually of a periodic Josephson’s Junctions (JJs) lattice and its very high sensibility may be obtained with the synchronization of the JJs using resonators of superficial electromagnetic wave [2]. These resonators realize automatically the synchronization of several hundreds of JJs, including the electro dynamical especial line like lattice [2]. The purposes of this article are: the analysis of the quality factor of the periodic JJs lattice, the optimal choice of the substrate for this system and the construction of the millimeter waves detector based on these elements.
